Best Cable Splitter for Comcast – 2021 Buying Guide

You have one internet cable inlet in your home. You need to connect it to multiple TVs, internet modems, or phones in order to have all devices running concurrently. Now, this would be physically impossible to do without a deceptively small piece of technology known as a cable splitter.

A splitter is essentially a tiny box with a small opening on one end where the input cable goes in and multiple coax cable outlets on the other end. These connect to the different internet-powered electronics in your home.

We tested the various products on the market to bring you our top picks for the best cable splitter for Comcast.

How We Tested and Compared These Products

Not all cable splitters are created equal. Some work the way they’re supposed to, and others – not so much. To save you from the latter, we sought to separate the wheat from the chaff to save you time and money when trying to figure out what the best Comcast cable splitter on the market is.

We were only interested in testing products from top manufacturers. We’re talking – GE, BAMF, Extreme Broadband Engineering, and Tolmnnts. Very few manufacturers in the country adhere to the same quality standards you get with these companies.

The other thing we were checking for was the number of compatible devices that work with each splitter. For purposes of this review, we were looking for products that work with TVs, set-top boxes, cable internet, and broadband modems.

Finally, we looked at durability. We excluded connectors that were not corrosion resistant. For this reason, we went for splitters that were gold-plated, nickel-plated, or had a Zinc die-cast housing.

How to Choose the Best Comcast Cable Splitter – Buying Guide

When choosing a coax cable splitter to split the digital signal for your TV or internet modem, the device you get directly impacts the signal quality. Of course, there are the standard considerations you need to keep in mind, like the manufacturer, housing material, compatibility, and warranty. Other than that, there are three main things to look out for when making your purchase decision.

Bandwidth Spectrum

While all coax cables rely on the same RG range of connectors, the difference between them comes down to their functionality. The reason for this has to do with the bandwidth of the signals they’re designed to carry. Here’s why.

If you get a coax cable splitter that doesn’t support the bandwidth of the signal input it receives, it won’t split the signal properly. This results in packet data loss and low-quality signal output. You need to check the bandwidth spectrum of the cable splitter to ensure it is compatible with the signal it’s supposed to split.

Most entry-level splitters offer a 5-1000 MHz frequency range, which is ideal for Comcast. If you want something a little more versatile that works with more devices in your home, consider getting a splitter with a 5-2500 MHz bandwidth spectrum.

Signal Loss

Regardless of the type of cable splitter you get, it’s going to have some level of signal loss. The higher this level is, the lower the image quality you’ll get. Always look out for devices that have a high-shielding structure around the internal circuit board. This minimizes digital noise and the overall signal loss. In the end, you’ll have a higher output. Keep in mind that the coax cable matters when it comes to signal strength.

Number of Splitter Output Ports

Also related to signal loss is the number of ports on the splitter. The rule of thumb to keep in mind is – the higher the number of outputs you have, the higher the level of signal loss you’ll experience. This, in turn, affects the signal quality your cable TV receives.

The best cable splitters for Comcast are the 2-way variety: One port for the TV and the other for something like a modem. The fewer ports you have, the lower the signal loss will be, resulting in HD video quality.


What is a Comcast Splitter?

Comcast is the largest phone, high-speed internet, and video services provider in the country. A Comcast splitter is essentially a coaxial cable splitter that’s compatible with Comcast systems such as Xfinity internet and Comcast Cable. The GE Digital Coaxial Splitter, BAMF Coaxial Splitter, and Extreme Coaxial Splitter are all examples of Comcast Xfinity splitters.

What kind of coaxial splitter should I use?

For DOCSIS HDTV or traditional cable TV transmission, consider getting a splitter with a 5-2500 MHz bandwidth range. A 5-1000 MHz splitter will suffice for medium to high internet speed if you just need Ethernet for phone and broadband.

Does a Comcast splitter reduce signal strength?

Yes, it does. All digital cable splitters result in some level of signal degradation, whether or not the other ports are connected. 2-way cable splitters result in the least amount of signal loss compared to devices with three or more ports, such as the Arris and DirecTV 4-way amplifier splitters.


If you’re in the market for a Comcast splitter, any of the options we’ve reviewed in this guide would be an excellent choice. Based on our tests, the performance of these devices was outstanding in every aspect – price, low signal loss, durability, and compatibility. They’re definitely worth checking out.
