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

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.

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.

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.

A little pricey but a good product

Great product, easy to install and works as advertised. Well worth the money. Thanks again!

I live in a rural area 90 miles from the TV stations. I have a large antenna with pre-amp on a 40 ft tower to pull them in. 75% of the channels were completely perfect, but a few (namely Fox who always seems to operate at half the power of others and always seems to conflict with another nearby Fox channel) were borderline or poor. I had a 3 way spiltter that I replaced with this distribution amp and it helped to settle reception on some channels due to the boost (not half power Fox though). It also - depending on weather - allowed pulling in some side band stations. Overall, happy with the product and performance. Via my TV diagnostics my signal to noise ratio was only 15-17 with the TVs automatic amplifier running at 50%.. After I installed this, my signal to noise ratio improved to 18-22 with the TV automatic amplifier down to 30%. So real results in a difficult long range environment. It additionally filters out interference such as 5G which is a problem in my area, this device solved that part completely.

Really does work. I had a long-range antenna that plugged into the tv. I could get all the channels, but half were pixilated or wouldn't come in at all. The preamp wouldn't work with the old antenna because it had a built-in amplifier. I Bought a cheap antenna without built in amplifier from Amazon and all channels are clear and receptive. I fought this problem for years and can't believe how easy it was to fix.

Prior to installing this preamp, I was getting 136 channels on my HDHomeRun. Not all 136 channels were watchable though. I'm roughly 35-50 miles away from the towers. Reception mapping tools online show my reception will be "fair" or "weak" on basically all channels. My antenna is a Range Xperts Long Range antenna. I have a relatively short cable run (about 25ft) inside to the HDHomeRun. First, I'll note you need an extra coax cable than what comes with this kit. It includes 1 coax cable, but since you need to use their powered splitter, it requires another cable. I had to order a new cable just to try this preamp. Anyway, I installed it as the instructions show and did a scan. I got 20 channels with high gain. I switched it to low gain and got around 40 channels. All the channels I tried with the preamp were glitchy, even the ones that were solid before. Side note: the LED indicator light is supposed to change from green (low gain) to red (high gain) but mine stayed green. I noticed another review that mentioned the same. I tried researching my issue and the only conclusion I came to was that this preamp adds too much gain to my signal and overwhelms the HDHomeRun tuner. This doesn't make a lot of sense since the signal strength is only "fair" for most channels. Maybe the definition of "fair" is too vague. It'd be helpful if the manufacturer specified the conditions when it's appropriate to use this preamp. Not only is it expensive, but it typically takes most people a lot of time to add or change their antenna setup considering when done right, they are high off the ground and not easily accessible. Based on other reviews, this preamp seems to work for the most part. However, it obviously didn't work for me and in fact, made my reception way worse. I wish other reviewers would list important details, like how far their towers are, their cabling setup, etc. I sent this back for a refund.
