Works great if....... June 14, 2017
Reviewer: John H. from Baltimore, MD  
Ultra mini 4 brought my farthest stations to clarity but only after I had used new cables. The cables used were spliced once and had compression fittings installed. Evidently they were poorly done as once I had replaced the old, used cables with new non spliced cables the unit worked flawlessly as before I had less channels than before with just my antenna. Keep this in mind that the less splicing the better on your install. I had no idea the difference that alone would make.

Solved all my problems April 3, 2017
Reviewer: Dean from Charlotte,NC  
I want to thank Channel Master support. I bought a Mohu  Omnidirectional antenna with amplifier that came with it. I have 4 TV's and only had a 3 way splitter . I hooked it up and got 54 channels a few grainy at times . When I bought a 4 way splitter and hooked I only got 17 channels. So that is when I called and asked their support team about what was going on. the support specialist told me I needed a Mini Ultra 4 amplifier. I ordered one and hooked it up today to my 4 TV's and WOW got 54channels again and all of them clear as a bell. Even when we had a severe thunderstorm with heavy rain and wind . It did not effect my signal.. Two thumbs up. Thanks again for the support and will recommend Channel Master products to anyone.

4 TVs working fine March 20, 2017
Reviewer: tvdaddy from 27713  
I am in zip 27713 and have RCA 751 antenna, which is similar to the Stealth 50, mounted in the attic.  The Antenna goes directly into the Ultra Mini 4 amplifier.   All the useful channels are coming in at 100% signal on each TV.  Each works better than when I was using another amp with one TV.  Well done.
