CM-3412 July 16, 2019
Reviewer: David from New Hampshire  
Product seems to be well made, but I could see no change when it was installed.  In fact it seemed to work the same, whether power was supplied to it or not.  I removed it and went back to the passive splitter that I’ve been using for years.  Needless to say I’m disappointed.

Works great - easy to install July 2, 2019
Reviewer: Anonymous Person from Campbell, TX  
I have had marginal TV reception for years from an ancient antenna in my attic. I had a few channels in the kitchen near the antenna drop but almost nothing reliable in the other end of the house. I can't get in the attic by myself to hook directly to the antenna, so I just ran a short cable from the antenna connection in the kitchen to the input of the amplifier. I then ran a cable to the kitchen TV and routed a 75 foot cable down the hallway to the bedroom (doesn't look great but it works). I applied power to the amp and then ran channel searches on both television sets. I got 66 channels on each one, and all of them come in solidly and without pixellation. Considering I have never had more than 8 channels, I think this is wonderful and I am more than happy with this device. I highly recommend it to anyone needing help with weak antenna reception. It is very easy to install.

More channels July 2, 2019
Reviewer: Ken from Kentucky  
I’m thrilled how well this works. I’m 65 miles from towers. I did get 12 poor quality channels. Now 40 good quality channels.

Reviewer: Dean E from Oregon  
First of all I’d like to commend Channel Master for their service! Easy ordering, fast delivery (arrived 2 days early) very durable construction. It goes in my Travel Trailer and works great for both TV’s. I recommend this amplifier!

signal amp. October 11, 2018
Reviewer: Anonymous Person from LA southern california  
We live in the LA area of southern California and we have pretty good signal strength from our antenna. But there are some stations that don't always come in. This device was able to give us more signal and most of the time I am able to get these stations. Haven't placed it outside (have to drill an extra hole for the power) but it seems to work just fine
