Best Cable Splitter for Comcast

In this day and age, connectivity is everything. We have become so accustomed to constantly being able to connect various devices in our home; both with wires and wirelessly.

And that means having additional equipment and devices that are of sufficient quality; that is – if you want to make sure that there are no interruptions in your streaming of content and communication.

This is as true for the International Space Station as it is for your Comcast cable at home. Let’s face it — in 2020, people rarely have only one TV in their homes.

More often than not, you need to connect more than one computer, monitor, laptop, or TV to a single cable source. And that’s where the best cable splitters for Comcast come into play. This deceptively small piece of technology is there to ascertain all of the utmost speed of your connections.

However, if you want to be completely sure that all of your devices will receive the optimal signals for your cable TV; you will need high-quality cable splitters.

These need to be of sufficient quality to help you maintain the integrity of your home connectivity system. If you do this right and purchase the right products, you will experience minimal possible connection loss while also being able to use multiple devices at once.

However, you must bear in mind that picking the best cable splitter for Comcast and achieving the robust connectivity that you want is not that easy.

Even if you’re a tech-savvy person, to begin with, you may simply not be familiar with niche products like cable splitters.

As you’ll see, there are quite a few factors to keep in mind here; including the quality of the product and its compatibility with the rest of your network. Any wrong choice here can severely impact the performance you can expect out of your network.

With that in mind, we’re going to explore some of the most important aspects of buying the proper cable splitters, present you with our top choices for Comcast, and explain any frequently answered questions that we’ve come across in our research.

Our Pick

GE Digital 2-Way Coaxial Cable Splitter

GE Digital 2-Way Coaxial Cable Splitter

This excellent gold-plated cable splitter is precisely the right pick for you if you want something of premium quality.

We’ll start this list off by presenting you with the very best coaxial cable splitter that you can use for two different televisions that you want to use with the same network.

Firstly, this is a multipurpose output splitter that perfectly manages to achieve even signal division. Its frequency range for input distribution is up to 2.5GHz; more than enough for Comcast.

Plus, you’ll find that there is no speed discrepancy between either of the splitter outputs. If you’re wondering if this kind of precision is even possible, you don’t have to; the distribution of the input signal is achieved with such evenness because power goes through each port.

That’s why the quality of the signal in the two splitter outputs is equal to the quality of the input from the Comcast cable.

If you’re not impressed with this techno-speak and want to know what this means for you in practice; it basically allows you to perform lossless data connections between different compatible devices in your household.

For instance, all coax devices like antennas and amplifiers can be connected with multiple HD TVs, Internet modems, etc.

And let’s not forget the fact that this is one of the best cable splitters for Comcast because of its gold plating. This isn’t a mere aesthetic choice either.

The golden plating means that you’ll have the best possible connectivity and power conductivity between devices. Plus, the gold also keeps the cable splitter from corroding over time.

Once you invest in this particular cable splitter, you won’t have to think about getting another one for years.

What we liked

Apart from the fact that this is a high-quality gold-plated product that doesn’t suffer from corrosion, there’s also the fact this cable splitter is incredibly light; so you won’t have to think about how it will impact your overall cable setup or weigh it down.

Plus, the installation process for this cable splitter is one of the simplest ones you can imagine. There’s nothing to it except plugging in your input cable and connecting the other two devices to the output jacks. Of course, that’s pretty much universal for all cable splitters.

Apart from this, you should also know that this is a waterproof splitter. Naturally, you don’t want to have water near electricity or cables; but if an accident does happen, this cable splitter is the last piece of hardware you’ll have to worry about.

What we didn’t like

This is an excellent device for sure, and there are only a couple of things that we didn’t quite love about it.

First of all, it lacks a male connector; making it less than ideal for some cable setups. And also, you can only use it with negative power as an input.

How we chose the best cable splitter for Comcast

Don’t worry, this isn’t the only among the best cable splitters for Comcast that we can recommend to you. However, while we intend on providing you with other options, of course, do know that there are more than a few cable splitters out there.

With that in mind, you’ll certainly want to learn about some of the criteria that we used while choosing the best among these products. That way, if you want to find other options elsewhere; you’ll still know what to pay attention to.

So, with that in mind, let’s think about this situation for a moment. You’ve just purchased a gorgeous big TV, but you want to put it in your bedroom; you’ve already got one in your living room.

And you’ve got one cable, and need to have two separate connections. In that situation, you’ll have to choose a cable splitter — but you’ll need to know its inner workings as well.

Basically, this is a regular input-output piece of hardware. It takes the input signal from a single cable and splits it into more than one output signal; how many of these you’ll have available depends on the kind of cable splitter that you’ll purchase.

There are many different ones for all needs; from a simple 2-output splitter that just divides the signal into two distinct parts, to a huge 16-way output splitter.

Years ago, people used to have all kinds of hassles with cable splitters due to a loss of strength in the signal. However, things are much better in that regard with contemporary cable splitters. There’s no modulation loss here, and the signal strength is largely maintained regardless of how much you split the input signal.

Of course, how well this is done also depends on the quality of your splitter as well. If you invest in a truly premium-quality splitter, you’ll be able to achieve the superb viewing experience that you want on all of your monitors and TVs around your home.

To summarise — the elementary function of your cable splitter is pretty much turning one input signal into two or more output ones. And the primary goal is to do so while also avoiding the signal becoming too weak to be effective. You want a splitter that provides the same level of signal quality as you’d have if you connected the input cable directly to the device.

Naturally, this is impossible to achieve in a 100% capacity. There will be some loss over the signal division and transmission; much like sound, this loss is represented through decibels.

With that in mind, you need to know precisely what you’re going to buy. For instance, you need to learn about how different splitters are used for satellite TV and cable TV. If you use a satellite splitter for Comcast, you may encounter significant signal loss.

Also, we advise thinking about your practical splitter needs before making a purchase. Generally, what you want to do is to buy a splitter that has a couple of output ports more than you really need at the time of the purchase.

You never know when you’re going to buy another monitor or TV, and you don’t want to have to get another splitter then.

There are also diplexers and signal amplifiers, that have some functions similar to splitters for cable TV. The aforementioned amplifiers have knobs that you can use to adjust the strength and duration of the output signal.

On the other hand, you use diplexers when you want to achieve a connection between an OTA antenna and a cable TV.

If the price is an issue for you, know that the number of output ports isn’t the only metric dictating how much you’ll have to pay for a specific cable splitter.

Models that allow for higher bandwidth transmissions are generally more expensive compared to low-bandwidth ones.

However, even the best cable splitter for Comcast won’t set you back too much money compared to other pieces of hardware that you’ll buy while setting up your home equipment.

Different Cable Splitter Types

Passive cable splitter

The most basic cable splitter is the passive one. We’re talking about a simple casing made out of metal that has one coaxial input, and two or more outputs. The signal from the coaxial input gets divided into the outputs without being layered.

With that in mind, you should know that the splitter itself doesn’t have any features for signal preservation or amplification.

As a result, the input signal will be divided and lose a significant portion of its strength. You can expect it to be weaker by at least 3db. If you’re using splitters with more output ports, the loss will be even higher.

Active cable splitter

On the other hand, you’ve got an active cable splitter. In essence, its function is the same compared to the passive one; except for the fact that the divided signal also receives a degree of amplification from the splitter itself.

If you’re going to connect devices over long cables scattered throughout the household, we recommend using one of these, for sure.

That will ensure that you get some boost and compensate for the almost certain signal loss that is going to happen. However, you should also keep in mind that active splitters need a power source in order to work.

Diplex splitter

There are also diplex splitters; as we’ve mentioned before, these are specifically used to combine antenna signals with satellite signals. The splitter itself is there to successfully direct signals into the proper devices.

For instance, you insert a coaxial cable from your source into the diplex splitter and it divides the signal into its appropriate destinations, like computers or televisions.

Switch splitter

Lastly, there are switch splitters. We’re mentioning them here solely because we’ve talked about all of the other kinds, but chances are that you won’t exactly need one of these unless you’re a professional who does field installations of cable TV.

If different offices or apartments make use of a single source of cable TV, these multi-switch splitters are there to provide signal division upwards of four directions.

These splitters are the most expensive, and they provide the biggest amount of signal amplification; pretty much only reserved for professional operations.

Nyrius ARIES Home HDMI

Nyrius aries home hdmi

This wireless transmitter comes with an infrared remote, allowing you to control it from afar. If you want to make any changes to its settings, you won’t have to sit in front of it as you would in front of old-time radio.

Plenty of people use streaming devices nowadays; this is nothing out of the ordinary. And if so, you need to connect these devices to the HDMI input slot on your TV; resulting in a huge mess in terms of your cable setup, and issues with subpar Comcast cable splitters.

However, that won’t happen if you use a wireless transmission system like the Nyrius Aries. This is not your usual cable splitter per se, and it’s the most unique item on this list, but it’s definitely a worthy alternative that we’d be remiss not mentioning.

Many people fail to stumble upon devices like the Nyrius Aries; but in reality, this wireless transmitter can provide you with a wireless HDMI transmission that’s of a great 1080p quality. That’s more than enough for any television, and it has a range of a hundred ft.

Basically, for people looking for HD streaming solutions, this is a jack-of-all-trades problem-solver for laptops, PC, DVD players, and PlayStation consoles.

Plus, this wireless transmitter has an insanely simple setup process. It’s pretty much the good old plug and play; seeing as you can use it seconds after unboxing. All you need to do is to plug it in and scan for available devices.

What we liked

The best feature of this wireless transmitter is that, logically, it eliminates the need for a lot of wires around your various content streaming devices.

All of these are replaced with two components. One is the primary HD transmitter that you can place both horizontally and vertically pretty much anywhere as long as it’s in range; this device contains all of the output and input HDMI ports.

We’re also satisfied with the fact that this transmitter isn’t difficult to understand and use. Most wireless transmitters and modems have a bunch of flashing lights that are difficult to distinguish between or make sense of.

Instead, this wireless transmitter shows only one LED indicator; the one that tells you whether it’s working actively or not. There’s simply no confusion with this device.

You can also place it in any interior due to the black color and its extremely sleek design. Also, the other part of this transmission device is its digital receiver. It’s smaller than the transmitter, and it contains source input jacks, power buttons, LED indicators, and different ports.

Obviously, the biggest draw of this device is the fact that it can transmit sound and video without any latency or compression; it will arrive instantly and be presented in its original quality. There will be no lagging, at least according to the manufacturers.

Apart from that, it’s also worth mentioning that you won’t have to perform additional software installations.

What we didn’t like

First of all, as high-quality as this device is; it can never reach the reliability of a wired cable splitter. Simply put, cables are always more stable than even the best possible wired connections; which is something you should keep in mind.

Also, while this is an excellent hub for streaming devices; consider the fact that this is far more expensive than even the best cable splitter for Comcast.

After all, it’s an additional piece of hardware, rather than a small accompanying device akin to a splitter.

BAMF 2-WAY Splitter

BAMF 2-WAY Splitter

This device comes with a zinc casing and a nickel plating above it; meaning there’s no insertion loss and quite a high isolation.

Next up, we’ve got a more traditional cable splitter; the BAMF 2-Way. This is one of those products with a seemingly generic but incredibly sturdy design. If you need something that’s built solidly and that can last you a long while, this is a splitter for you.

It contains a circuit board that’s built-in and makes sure that the signal loss during the division is minimal; this is one of the active splitters that we’ve previously talked about.

It can provide you with bi-directional transmission at an astounding range of frequencies. And the reduction of transmission losses goes up to 3.5dB, meaning that most devices that are near each other won’t experience any loss at all.

What we liked

The design of this cable splitter is completely oriented towards high shielding; meaning that the reduction of digital noise is some of the most effective ones you’ll find on the splitter market. There aren’t many cable splitters that preserve signal quality quite so well as this one.

All of the ports found on this splitter can allow you to direct signals towards all kinds of devices; from satellite antennas to cameras, TV, amplifiers, etc.

The F connectors found within are perfectly capable of transmitting 24V at a 0.5A current towards several different outputs.

Plus, it can be used as something of a signal combiner; for different antenna systems, or your television and your phone.

The designers of this splitter were cable technicians themselves, meaning that they know just what the end-user needs. With that in mind, know that this splitter works with different coax cable sizes, meaning it’s more versatile than most others.

What we didn’t like

One of the rare issues found with this connector is the fact that it doesn’t function as a two-way splitter; somewhat limiting the versatility of an otherwise excellent cable splitter.

Extreme 2-Way HD Digital Splitter

Extreme 2-Way HD Digital Splitter

There’s also a nifty feature for universal mounting, which makes the product suitable for any part of your household while eliminating the need for any other hardware besides this.

The final among the best cable splitters for Comcast is another excellent active amplifier. This Extreme Coax Splitter represents one of the very best products in its niche.

You’ll find that this uniform splitter gives you everything you need for an excellent level of connectivity between your household devices.

Sure, this is something of a simple product; it’s only a basic two-way splitter. Still, it has plenty of quality of life features that allow for an excellent degree of usability.

We should mention the fact that the 1ghz frequency makes this product extremely suitable for the establishment of all types of coax connections stemming from a single router of any kind.

The design is impeccable in other ways as well; for instance, the F-ports on the splitter are sealed, allowing you to use this splitter in the outdoors as well. Indeed, it’s safe to use in all kinds of conditions. No moisture or humidity will harm the functioning of this cable splitter.

What we liked

All of the things that we’ve mentioned above make this product a more than worthy addition to any household.

And on top of that, this splitter comes in a zinc housing that’s present in both the back and the front of the device; meaning you don’t have to worry about corrosion that can happen with other metal casings used in the outdoors.

As you can see, longevity is something that we value extremely when it comes to the best cable splitters for Comcast.

After all, even when you make a mild investment into something, the last thing you want is to have it break down and repeat the purchase after a couple of months. This final cable splitter falls into the category of sturdy and dependable products as well.

The 15PSI internal air pressure in the components makes them completely waterproof and safe to use in all kinds of weather. Plus, the technology used for the insertion of all the electronic components over the course of manufacturing has ensured the utmost performance of the product.

As we’ve already talked about, the universal mounting feature allows you to put it pretty much anywhere and use it in any direction. You won’t need any additional screws or mounting gear to set it up anywhere in your home.

What we didn’t like

We have to mention that there’s one thing which we weren’t thrilled about regarding this product.

Some users seem to have reported that the product doesn’t work well with a couple of more obscure router models, causing them to become stuck in a restarting loop.

However, this isn’t a major concern as we’re talking about one or two router models out of literally thousands.

Buying Guide

Now that we’ve taken a look at some of the more reputable models of the best cable splitters for Comcast, we’re going to talk about some of the things you need to know while buying one of these; or any other cable splitter, for that matter.


The first and foremost aspect of cable splitters is simply the number of splits you have available on the product. Or rather, the number of output jacks for your divided signal to travel through.

Most commonly, you’ll find cable splitters with two splits. That’s because this is something that’s most needed for usual household use.

On the other hand, there are plenty of other, more versatile cable splitters you may pick from. As we’ve mentioned already, we advise buying a splitter that has more output jacks than you currently need. That way, if you happen to need more at some point in the future, you won’t have to switch out for another cable splitter.

While this will save you a lot of hassle, it also doesn’t mean that you should buy a huge cable splitter that’s industrial-grade; those may simply take up too much space.

What you want to do is to go with something in between; a number of splits that’s guaranteed to satisfy your hardware requirements in the near future, but without going overboard.

Having more splits than you actually need can be detrimental to your signal strength as well; the more splits you use, the weaker the signal will be.


The most generic and affordable two-way splitters won’t do anything more than divide your cable signal into two. If your output devices require a lot of signal strength, this might not be ideal.

That’s why higher-quality devices for cable splitting come with signal amplifying features. We recommend buying these if you’re going to use the splitter to drive signals to more powerful electronic devices.

There are also combiners — products that not only have the option to split but to combine as well.

So, what does this mean?

Basically, in its simplest form, this is another splitter with one input jack and two output ones. However, these are two-way splitters. In other words, you can also use the output jacks as inputs — allowing you to combine signals from two devices into one output signal.

This isn’t a feature that you might necessarily be looking for if you’re trying to find a decent cable splitter.

However, you never know when your electronic setup might change in the near future. That’s why we recommend getting these more versatile splitters for Comcast, if possible. Having this function as a possibility is definitely a great boon for the future.

Picking Cable Splitters

Considering everything else that we’ve talked about above, the real question is — what are some of the most important factors to take into consideration while picking your cable splitters?

Apart from the things we’ve already discussed, you should also think about the splitters’ capacity. And yes, we’ll have to get a bit technical on this.

However, suffice to say that this is a metric represented in gigahertz and megahertz — GHz and MHz, respectively. As you might imagine, a single gigahertz contains a thousand megahertz.

If you need a point of reference, a standard cable television operates with a signal of about 1GHZ.

Before you pick the splitters for your specific machines, you’ll have to look at the level of capacity that your devices require.

Not doing this may mean accidentally choosing subpar splitters that end up slowing down your signal and triggering malfunctions on your other devices.


At the end of the day, no matter what you’re buying — the cost is still one of the biggest deciding factors when you make your pick. And in this regard, even the best cable splitter for Comcast is no real exception.

Now, the top products that we’ve showcased here have a capacity of 1GHz. However, there are some more expensive ones out there with even better bandwidth capacities.

Naturally, these will set you back a bigger sum, but more demanding electronic setups may simply demand this; at least if you care about maintaining an optimal connection speed.

Frequently Asked Question

Now that we’ve covered some of the finest products on this market and shown you what you should think about while picking your cable splitters; we’re going to answer some of the most frequently posed questions regarding this piece of hardware.

How to use a cable splitter for TV and internet – Comprehensive guide

While using a cable splitter with a television set isn’t difficult, plenty of people don’t actually know how to do this. No matter, though — learning how to do this isn’t difficult at all.

There are a couple of things you’ll need in order to perform basic functions with your cable splitter. First of all, you’ll need to buy the actual splitter; that much is obvious. Then, you’ll need coaxial cables, a guide for your television ports, and a couple of pliers.

If you want to connect your television to the splitter, the first thing you’ll have to do is disconnect the current cable line. In fact, plug it out of all the hardware that it is attached to as of now. Then, take a look at your port guide to see which the main ports are.

Once you’ve disconnected the current setup, attach your coaxial cable to the input jack on the cable splitter. After that, you need to connect the output coaxial cables to the splitter as well and tighten the screws with pliers so that the connection isn’t interrupted by their falling out of place.

Another tip: make sure that you have a coaxial cable that’s lengthy enough before trying to change your TV setup. Obviously, the length that you need will largely depend on how many devices you intend on connecting to the television set. Also, be careful not to tighten the screws with the pliers too much and damage the internal part of the cables.

Once you’ve done all of that, you need to simply turn your cable TV receiver on — and voila! Every single device that you’ve connected via the cable splitter should now have a cable signal. You can now watch whatever you want on as many screens as you’d like.

Does a cable splitter affect quality?

Many people who use cable splitters for their connections wonder if using one might degrade the quality of the content that you see.

Directly, that’s simply not the case. The cable splitter that you use cannot directly impact any of the audio or the video that you stream using the cables connected to the splitter. The only thing that might happen is the possibility of stuttering or lag, or perhaps a complete loss of the signal.

If you think that your cable splitter is the part of the chain that’s causing the lag, make sure that you’ve checked out all of the other possibilities first; after all, there are more than a few things that can impact the quality of your Internet connection or video and audio streams.

And if you’re completely certain that it’s all about the cable splitter, check to see if any of the input and output cables have been dislodged from their jacks due to loose screws.

Put everything back into place and tighten it; if you’re still experiencing issues, your best bet is to try with another cable splitter. Should that fail to fix your issue, you can be pretty certain that the problem wasn’t being caused by the cable splitter, to begin with.

Does TV splitter weaken the signal?

While a cable splitter can’t exactly affect the content that you stream, it can affect the strength of your signal. And we’ll say this right away — even the most basic cable splitter without an amplifier will negatively impact the signal strength. And that’s true even if you don’t use all of the output jacks on the splitter.

Don’t worry though, there are certain measures that you can take to mitigate this.

For instance, you can place terminator caps on the ports that you don’t intend on using. These will not completely eliminate any signal degradation, but they will help to a certain degree.

Additionally, know that picking some cheap splitters might mean different signal degradations at different ports; so you won’t know which to terminate and which to use.

Note that there are different factors that influence just how much a splitter impacts the quality of your connection. For instance, there’s the ratio between the signal and its noise. If you want to maintain a stable connection at most times, try to keep this beyond 32dB.

Apart from that, there’s also upstream transit. If it’s above its default value, you will find your modem struggling to transmit information back to your system of cables.

As a result, it will make more frequent and harder attempts; continuing to do so before the modem overheats, restarts, and begins the process again. Naturally, even if managed, frequent overheating will mean long-term damage to the entire system. You should also consider receiving power as well.

But the real question is — how does your cable splitter affect these metrics?

The ratio between signal and noise won’t be impacted a whole lot, but you should expect it to be reduced by at least one dB.

Additionally, your upstream transit is likely to be raised by at least 3 dB; vice versa for the downstream, which will be decreased for the same value.

If you really want to get into precisely how the splitter affects your signal strength, you can always look at the current status of these values on the diagnostic page of your modem and make the required additions and subtractions.

If the values you come up with remain in the range of functionality for each metric, everything will be fine.

Does a cable splitter affect internet speed?

Using a cable splitter with your cable internet connection might be a good thing if you need to connect multiple devices.

However, the question remains — will this reduce the actual speed of your internet connection?

Every homeowner would like to learn the answer before beginning to change the internet and cable setups in their household.

The cable company that you have a contract with will have the proper answer to this question because they know precisely which splitters they use in the field. However, if their representatives can’t answer this question for you, we’ll help you find out for yourself.

First of all — know that a properly installed cable splitter should not bear any noticeable impact on the speed of your internet modem. That being said, there are a couple of metrics that your splitter can have some bearing on; but speed is not likely to be among them.

We recommend taking a look at the strength of your wireless signal before you install or change any cable splitters. If you’re dealing with a weak signal, to begin with, the chances of running into trouble with additional splitters become much higher.

However, decently robust signals should be presented with no issues at all. Still, that’s why checking out your signal before you put in a new splitter and after it’s been installed is a very good idea.

If you notice that your Internet speed has been negatively impacted by the splitter, you should definitely try another splitter model. And if that doesn’t help, you need to contact your cable company.

They should be able to produce another cable line to your household and avoid the usage of splitters in your home altogether; that might cost you additional money, but it’s not really avoidable if your connection doesn’t play well with splitters.

However, you should know that this is rarely an issue with a majority of home connections.

Does the length of the coaxial cable affect the signal?

We’ll answer the most basic part of this question right away before getting into the details. Indeed, the length of your coaxial cable will affect your TV or internet signal.

In fact, the length of the cable will adversely affect the signal strength; the bigger it is, the worse your signal will be. In short, this is because coaxial cables aren’t a perfect transmission system. If you use them, the degradation of the signal will be an issue over bigger cable lengths.

There isn’t too much sense in getting into the weeds of the strength of radio signals, transmissions, cable impedance, and other aspects.

Suffice to say that there is a simple rule of thumb that you can use while judging how badly your system will be impacted.

Pretty much, you should know that anything below 50 feet of cable length won’t result in any signal loss that you can actually notice. However, anything above that means dealing with signal issues.

Furthermore, a cable that’s longer than 100 feet means that your signal strength will be severely impacted; by some estimates, it will lose a third of its original strength.

Obviously, this is an issue for bigger households with antennas on the rooftop. Naturally, some parts of the house might receive slower signals in this situation.

But if we go back to an electronics set up in a single living room — a cable that’s about 15 feet long won’t result in any of the issues that we’ve talked about above. If there are no other factors that could cause signal interference, your television and computer will receive something that’s as close to the original signal as possible.

What does DB mean on cable splitter?

In order to understand the impact your amplifiers and splitters have on your Internet connection or TV signal, understanding dB values is an essential factor.

First of all, you should know that this isn’t a precise value of signal strength. Instead, it’s simply a relative value. It shows the strength of your current signal compared to its previous strength before the splitter.

Let’s say that you’re using a simple 2-way cable splitter. If you take a look at it, you will most likely see a 3.5dB mark. However, that doesn’t mean that the strength of the output signal will be 3.5dB. Instead, it means that the input signal will be lower for that value once it exits the splitter.

But how much is that actually?

This is determined by a logarithmic piece of math, and there are tables that provide you with quick decibel loss values compared to how they impact your actual TW signal.

What kind of splitter does Comcast use?

Cable companies like Comcast usually provide their own splitters during installation.

However, if you need to purchase your own for whatever reason — there are different splitter measurements in terms of cable thickness.

Make sure that the splitters for Comcast setups are compatible with RG6 cables. We recommend avoiding most gold-plated splitters in this situation, though there are a couple of ones that you can definitely use — like the model we’ve recommended above.

Just remember that these setups won’t require any monster splitters with double-digit numbers of jacks; any high-quality splitter with a couple of output ports will do. Also, your splitters will need to be at minimally 1Ghz capacity.

How many splitters should be on a cable line?

The number of splitters that you’re going to use on your cable setup directly depends on the number of output devices that you’re splitting the signal for.

Generally, we’d recommend consulting a professional who knows more about cable installation than the average layman. However, you should also keep in mind everything that we’ve talked about already if you’re going to do it yourself.

Namely, the fact that having more than one splitter means having additional output jacks; all of which are likely to reduce the strength of your signal if you don’t plug them with terminators.

At the end of the day, asking your cable company to perform the installation might be the most worthwhile way to go about it.

Many of those companies don’t even charge an installation fee — and they already have all of the necessary equipment, including the best cable splitters for the job.

However, if you find that even a single two-way cable splitter is causing interference; you’re going to have to use a splitter with a built-in amplifier.

How can I split my TV into multiple TVs?

If you want to use a single cable source with different TVs in your household, that should be no issue at all. You won’t need more than a single cable package if you use the splitters in the right way.

The first step here is to locate the main cable line that goes through your home. Then, after you’ve determined the best possible splitter for this task, you’ll have to connect the splitter to the main signal line.

If you only intend on hooking up two TV sets to the cable, you won’t need anything more than the most basic two-way cable splitter. Anything more than that will require a four-port splitter that’s more powerful, but more expensive as well.

Regardless of the number of output devices, your next step is to connect every output jack to the cables for these devices.

If you’re connecting a multitude of TV sets, we recommend finding the best possible RG6 cable; you’re going to need high-quality cables if you want to minimize signal loss over bigger cable distances. Once you’re done with that, all that’s left is to turn everything on and see if it works.

What is the best coaxial cable for the Internet and TV?

We’ve already mentioned that having good-quality cables will have a positive impact on your TV signal; the same goes for your Internet connection, so you need to make sure that you’re dealing with a great coaxial cable. With that in mind, we’re going to repeat our recommendation from above — an RG6 cable will be the best possible thing for your TV.

If you really care about pedantry, an RG11 cable is specifically made for HDTV signals and will transfer such signals at slightly better speeds. However, it’s important to note that there isn’t that much of a difference between these two.

Do you need a separate cable box for each TV?

No. If you use cable splitters, you’ll have no trouble dividing a single signal into multiple output signals for your television.

However, there is a situation where multiple cable boxes might be a necessity. If your household is simply too big for traditional coaxial cable use without signal loss, then a couple of local cable boxes will simply have to do the trick.

Though, remember that these usually mean having multiple cable contracts as well.


As you can see, even a small piece of hardware like a cable splitter can have a huge impact on the quality of your cable and Internet connection.

With that in mind, we recommend making your choice carefully, and by keeping our guidelines in mind. We hope you have learned something new about the best cable splitters for Comcast today. Stay safe and have a good one, guys!
