better than expected October 11, 2018
Reviewer: Dan Johnson from Iowa  
I have a pre-amp with a CM Extreme 80. I have added the Mini 4.  It is performing great.  In-fact it may have improved the quality of the picture.

Nice! July 10, 2018
Reviewer: Canandaigua Man from Canandaigua, NY  
I have this unit installed in a system consisting of a Digital Advantage 45 paired with a CM-7777 preamplifier with about 100 feet of RG6 coax. Reception is excellent, even for channels needing a Purple-rated antenna.  No dropouts or pixilation at all and I receive all local TV channels.

Amp Helped May 22, 2018
Reviewer: Anonymous Person from Greensboro, nc  
Seemed like their amp was the way to go along with their 60 mile antenna. Brought in the majority of my local TV channels much better than the "in the window" HDTV antennas. Seems like a good solid quality built unit but it was very disappointing that Channel Master doesn't have a longer warranty period. For a business that has been in this line of products I would think it would be at least a year or 2. Time will tell on how long this unit will last and if need be where I will get a replacement.
