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.

Solved my problem March 31, 2017
Reviewer: David from Florida  
I receive around 60 channels from about 45 miles from the broadcasting towers but I was not getting a 100 percent strong signal which resulted in some channels like NBC dropping the signal in evenings.  I added this and it boosted most channels to 100 and others I was getting signal drop to the high 80s.  Works great and solved my issue.
