Ultra Mini Amplifier January 28, 2016
Reviewer: Kent from SE Wisconsin  
Excellent product. Allows us to view over the air programming from a small rooftop antenna with improved reception. Eliminated the pixilating from the more distant stations. Will highly recommend this to others.

Nothing is Free...including TV December 30, 2015
Reviewer: Ken Clawson from Casa Grande/Eloy AZ, 85131  
The Ultra Mini 2 is a must in my application. Before I installed it the Smarttenna was no better than the old analog system it replaced, Omnidirectional does not mean what I thought it meant. But now the channels I do get are clear and crisp with good sound. The area I'm pulling from is about half way between Phoenix and Tuscon, 50 miles either direction give or take a few. I still cannot pull channel 12 in and have 100 bucks invested. There are better systems out there for the money spent. My neighbors have competitors equipment with the same investment that can get more channels including the illusive channel 12. My RV antenna by Wyngard beats them all in the same exact location..

Good product, Not For My Situation February 2, 2015
Reviewer: John Whitney from Atlanta, GA United States  
I have a very long run of coax from antenna to splitter serving TV and DVR+.  The Ultra Mini 2 did not help at all - reception was unchanged (still had dropouts, depending on the weather).  Multiple emails to/from Support resulted in the determination that an antenna preamp was needed, not Ultra Mini 2.  I felt the advertised description of the unit was misleading.  I have had good results with the DVR+ from Channel Master, so I thought this product would help.  I may try a preamp, or just live with occasional bad reception.  I am inside a large metro area.
