4 TVs working fine March 20, 2017
Reviewer: tvdaddy from 27713  
I am in zip 27713 and have RCA 751 antenna, which is similar to the Stealth 50, mounted in the attic.  The Antenna goes directly into the Ultra Mini 4 amplifier.   All the useful channels are coming in at 100% signal on each TV.  Each works better than when I was using another amp with one TV.  Well done.

Perfect performance March 20, 2017
Reviewer: B. Thomas from Allen, Texas  
I needed a splitter to serve four TV's locations in my home, but decided to use this amp for that function because of long coax runs. Signal strengths at all TV's are maximum levels. Very pleased with this product.

To be considered March 8, 2017
Reviewer: Ralph from Phoenix  
The amplifier supports 4 devices, which increased the antenna from 38 channels to over 80 channels with much better qualility.

signal amplifiers February 22, 2017
Reviewer: Ed from Hebron Illinois  
Made the break from cable recently, but because of the long runs of coax in my house, only a couple of channels came in. I installed a mini 2 at the beginning of the run and a mini 4 where the cable splits to all the rooms. Four TVS with 50 channels with crystal clear reception! Already have several friends and family members ready to do the same. Will be ordering more soon.
