CM-7779HD PreAmp 1 TV Antenna Amplifier with 5G LTE Filter, Adjustable Gain Preamplifier - Professional Grade Signal Booster

Works great for me! In my area this is the best! Hopefully longevity is good!

I purchased this to replace a similar device that died after many years of service. (10 plus) The old amp I was using also had a high and low gain setting. I have a large antenna, (not the biggest by any means), suspended from rafters in the attic of a two story house. I live in a very rural area, miles away from any station in NE Ohio and can only pick up 3 channels without an amp, and a poor signal at that. I got this connected up and on the low gain setting am now receiving 72 channels on my Tablo TV tuner. Of course many are duplicates but still. Although my antenna is directional, I'm picking us stations from all around me. Sometimes, due to atmospheric conditions, being able to pick up things from other directions can be beneficial. An important note: Others have mentioned this but it bears repeating. More power does not always equate to better reception. Any amplifier boosts both the signal as well as the noise, so keep that in mind. It is also important to locate the amp itself as near to the antenna as possible. In my case, that is near the antenna in the attic. In my application,17dB of gain works great. It is nice to have restored all the channels I had before the old unit died.

This channel master amplifier was installed inside our farm house, in the middle of nowhere. Channels are tough to get with an antenna because of distance and our metal roofs. We could get some Channels but the digital channels would digitize a lot and some days, would not even come through. We purchased this product in hopes of picking up and maintaining channels. We found we couldn't get more channels but the clarity of our current channels blows us away. The channels are crystal clear now. Don't necessarily buy this product to get channels, buy it to clear your current digital channels to crystal clear ones, with no digitizing. This amplifier does work and I feel confident recommending it in Canada.

Did not help OTA antenna amplified signal

This powered TV amplifier works extremely well. At high gain, it increased the number of digital channels received from 20 to 38 and significantly improved picture quality to cable channel level. The device offers 2 levels of amplification: low and high gain. High gain provided the best results for me given my antenna being located in the attic and the distance to the broadcasting towers (45-55 miles). It was easy to install and very well made. I highly recommend the product.
