Signal Boost for Long Runs March 13, 2018
Reviewer: Anonymous Person from Gilbert, AZ  
A couple of my sets are up to 200 feet from my antenna.  This amp really cleaned up the signal and so far has eliminated all of the pixelation I had been getting previously.  The Channel Master support was exceptional and everyone went out of their way in a very friendly manner!

Channel Master December 18, 2017
Reviewer: Anonymous Person from Beverly MA  
I have used 2 generations of Channel Master DVR s for 12 years.  The newer generation is reliable and is better at receiving a weaker signal than any of my TVs (Sony or Samsung.)  The ultra mini works better than my prior Radio Shack amplifier. With an outdoor Radio Shack or Winegard UHF antenna and quad shield cable mounted in my attic I can reliably receive -50 dB stations, (50 stations without rotor).

Helps my signal. November 2, 2017
Reviewer: Anonymous Person from Rochester, NY  
I had one station that would go in and out almost all the time and another station that would go in and out when the weather was bad. With the Ultra Mini 2 I am able to watch both stations even when it is windy or raining. I connected it to the cable which comes down from an attic antennae.

Ultra Mini 2 Port Saves the Day October 3, 2017
Reviewer: JT from Ohio  
The Ultra Mini 2 Port is a simple way to amplify the signal from our 65 mile range chimney mounted antenna.  Our 20 year old Archer quit, so we faced a dilemma:  install a Titan 2 Med or Hi Gain preamplifier at the antenna mast OR install a signal distribution amplifier at the distribution point in the basement at the end of the 75 ft long antenna coax run.   We opted for the Ultra Mini 2 at the basement branch point for two additional 25 ft runs to 1st and 2nd floor.  Without it we receive 0-4 channels.  With it we receive 27 clear channels out of 69 possible.   If you want to receive all possible channels in your area then install the Titan 2 Medium or Titan 2 High Gain Preamplifier at the antenna mast (no further than 10 ft from the actual antenna) and then also use the Ultra Mini as your signal distribution amplifier.  But if you only need a subset of the total available channels then simply install an Ultra Mini at your branch point.

Works Great August 29, 2017
Reviewer: Anonymous Person from Griffin, GA  
When I decided to cut the cable, I tested an antenna on one TV, but when I installed it with a splitter, it suddenly did not work as well, after consultation with people from Channel Master, I made this purchase, and it has restored the signal to what it was before the signal was split.
