11 Best Cable Amplifiers 2023

At times a high-resolution TV alone isn’t enough if you want to enjoy life-like pictures. That’s especially true if you have several television sets sharing the same signal source. As you split your signal cable for different TVs, the signal quality deteriorates.

Also, as the transmission distance increases, the signal strength gets lost in the way, thus becoming weaker and weaker. That’s why you are likely to struggle to see where the ball is when watching a big game on the TV that’s furthest from the signal source.

So, what next?

Well, having each TV have its own source is one way to improve the image quality. However, it can be a little expensive, especially if you have several TVs. And that’s where a cable amplifier comes in.

A cable amplifier works to boost the TV signal. By doing this, it ensures that you take full advantage of your TV’s high resolution. Just be sure to place it in the middle of the long cable for you to make the most out of it. With us today are the 11 finest cable amplifiers.

Frequently Asked Questions

What weakens cable signals?

Well, there are several factors. First, long cables. As the transmission distance increases, the signals encounter more noise and attenuation, and that results to signal loss. Also, during splitting, the signals get distributed into the resulting different outputs. When you split the main signal source into two, each outlet port will carry 50%, resulting in poor picture and sound quality.

How do cable amplifiers work?

As the name suggests, cable amplifiers work to boost TV signals by increasing the (dB) of the outgoing signals. It ensures that the outgoing signal strength level on each port matches that of the main inlet cable.

Do I need a cable amplifier?

If you have multiple TV sets in your home, then the need for a cable amplifier is more likely to be there. Also, if you live in remote areas far from the broadcast towers, a booster is necessary for improving the signal strength.

How many TVs can one antenna support?

It will depend. A mere coaxial signal splitter may not work well as signal loss happens during splitting, causing weaker signals beyond the splitter. However, with a cable amplifier, you can split the signals when retaining their initial strength. The number of TVs your antenna can support will depend on the number of output ports on your amplifier. Some models will allow up to eight TV sets to share the same antenna.

Will a cable amplifier help my Internet?

Although that’s not their primary purpose, some members report improved internet speed when using cable amplifiers. Therefore, it’s really hard to tell whether your cable amplifier will improve your internet speed or not.

Final Verdict

There are a thousand and one reasons why you should have a cable amplifier. Although they work like normal coaxial splitters, cable amplifiers have the added advantage of boosting the signals.

Therefore, they work to ensure the most efficient cable signal distribution. Unfortunately, they don’t all guarantee the best performance. That’s why we’ve brought you some of the market’s most recommendable options.
