Back in the day, if we had 2 or more television sets, we needed to buy as many cable boxes. Using the same one and saving money felt like a distant dream. Thankfully, things have changed and technological advancements have enabled us to get seamless connections without spending a lot of money. In this article, we will shed light on this and help you with the solutions.

How to Extend Cable TV to Another Room?

Solution 1 – Choose a Cable Splitter

Cable Splitter

A cable splitter is a neat little device that will solve your problems in an instant. Thanks to these, you can extend cable TV to the bedroom or any other room at home seamlessly. The biggest benefit here is that they are affordable and easy to install. In fact, if you have basic DIY knowledge about wires and cables, you will be able to do it yourself.

The other side of the coin is not so bright, though. A cable splitter, because of its length (more than 50 feet), may cause signal loss. Also, you will not be able to watch separate channels on different TV sets unless you pay your cable provider extra money for the service. So, this downside will add up quickly and swell the cable bill every month. 

Solution 2 – Choose a Wireless TV Transmitter

Wireless TV Transmitter

A wireless TV transmitter still works with a cable splitter but it will solve the problems we mentioned above. This is because in this case, you only need a short cable to connect the splitter to the transmitter. So, you won’t have a long cable running in your house and signal loss will not be an issue anymore. 

With a wireless TV transmitter, you will also be able to enjoy multi-device screening and not stick to the same channel on all TV sets. 

However, we must inform you that this method is not devoid of cons either. For one, setting up a wireless TV transmitter is expensive. Also, it takes up a lot of the Internet to give you the desired result.

Make sure you compare the pros and cons of both these options before you choose the best one for your requirement.

People Also Ask (FAQs)

Here are a few FAQs and their answers to help you understand this further.

Are Cable Splitters Illegal?

No, there’s nothing illegal about cable splitters. 

How Many Splitters Can You Put on a Cable Line?

We suggest that you only use one splitter to avoid signal loss. You may choose a 2-way or 3-way splitter based on your requirement. 

Is There a Difference in Cable Splitters?

Yes, you will see a difference in quality and the capacity.

Does a TV Splitter Weaken the Signal?

There may be a slight signal loss but if the installation was done right, this won’t be a concern. In case you are experiencing problems, we advise you to use an amplifier.

Does the Length of the Coaxial Cable Affect Signal?

Until 50 feet, you won’t experience signal loss. You will start noticing a drop from 50 feet and it will keep getting more significant. At 100 feet, you will experience 1/3rd signal loss.


You don’t have to spend money on an extra cable box to use 2 TV sets. You can easily extend cable TV to another room using a splitter and wireless transmitter. Even though they are more expensive than splitters, our vote goes to wireless TV transmitters because they are more efficient and helpful. Also, they cost less than separate cable boxes. We hope this helps. You can always comment or get in touch if you have any more doubts.
