## Description

desertcart.com: Channel Master TV Antenna Booster 4-4-Port TV Antenna Distribution Amplifier, Built-in LTE Filter, 7.5dB Gain, Compatible with Non-Amplified TV Antennas, Increases Signal Strength, Indoor/Outdoor : Electronics

Review: Trusted Brand and Works Great - Had to replace my old powered 8db gain per channel Splitter( different brand) due to power failure surges. I live in a rural area. I went with this 7.5db gain per channel Splitter(close enough). This is very sturdy, seems to be well made. Has a little weight to it which surprised me. Very easy to hook up and works well with no loss I can see. Also, had to replace the 28db PreAmp( different brand) at the antenna. Used the Channel Master adjustable 17 to 31db gain PreAmp. Even set at the low end I am able to pick up about twice the amount of channels during a scan. Picture very sharp and clear. Very pleased with these units and Channel Master.
Review: It works. Strengthns the signal and supports its distribution to several TVs. - I was having a hard time with the Antenna signal strength, especially distributing it to the 4 TVs in the house that are quite apart, with long coaxial cable runs. I replaced an aging splitter/amplifier with this one and the results are nothing short of amazing. Instead of 60+ channels, TVs capture 106 channels! All with solid signal. So if have a similar case, this is well worth a try. It made a difference, and resolved the occasional frustration with weak signals that would cause pixelation.

### ⭐⭐⭐⭐⭐ The darn thing actually works!
*by J***R on December 26, 2025*

I live in the mountains surrounded by trees. I have a good digital over-the-air antenna, but I live far away from most of the TV signals. Mountains, Trees, Distance. If you want to kill an over the air signal that's how you do it. I've tried a half-dozen of these booster things with virtually no benefit, and honestly I was hesitant to buy another one. I'm familiar with the Channel Master brand, so I rolled the dice and decided to give it a try. I was ready to accept failure once more, and was startled that my reception increased by 40%, maybe 50%! Signal strength for existing channels and I'm now receiveing channels that I didn't know existed. I changed nothing with my antenna or conditions. I simply added this to the antenna line that feeds three TV's and plugged it in. It works great! I'm very surprised. Now I'm an electrician so installing this was easy for me, and in reality if you have an electrical outlet that can be used to power it, and are capable of attatching the TV co-ax cables, this is an easy installation. If you need someone to help you, don't hesitate, it's an easy install for someone who is versed in such things. This is an easy 5 stars. I'm still surprised and very pleased at how well this Channel Master Booster works. I didn't think it could be done.
