Ultra Mini/signal improvement December 13, 2016
Reviewer: Art from Milwaukee  
My Ultra Mini has greatly improved our reception, which was previously plagued by frequent break-ups.  The Mini provides a good strong signal to 4 locations in our home that are fed by coaxial cable previously installed by a cable provider, which we no longer use thanks to the Mini and our DVR Plus.  I look forward to even better reception from more channels when the weather improves and I can get out on the roof to install my new stealth antenna.

works marginally November 11, 2016
Reviewer: Oscar from Chicago  
It amplifies the signal a bit but it is not enough for 3 TVs even after using a terminator for the empty out.
