Excellent results - the difference was amazing! July 30, 2018
Reviewer: Mick from Alabama  
The signal from my antenna into my home Connection Center was not strong enough to send a good signal to all 6 tv’s throughout the house. After adding the Ultra Mini 8 all channels are coming in perfectly clear for all 6 tv’s now. Simple straightforward installation that works perfectly.

Excellent distribution amp.  Went from splitters to this distribution amp and my signals at each television increased considerably.   Thank you Channel Master!

The perfect multi-tv off-air solution! March 13, 2018
Reviewer: Anonymous Person from Detroit area  
Finally cut the cord with cable and installed the Ultra 60 antenna and used the mini-8 to feed 5 sets in throughout the house!  Simple to install, flawless performance. In fact, the opinion of family members is that the off-air HD signal they now each have is superior to the HD cable images we left behind; and, we still have three unused ports left! This just works, -- period.

Whole house amplified distrubution for cable TV November 20, 2017
Reviewer: Gary D from Marion, IA  
Wired the house when we built many years ago, but with cable TV frequency ranges changes over time the splitters didn't cover the full range needed.  Saw the 8 port ultra mini on line and thought this would give the whole house the proper signal strength and frequency range required for proper operation of our TV and cable modem for internet.
