5 of 5 Works great April 14, 2020
Reviewer: Wordmonger from Central Illinois  
I needed to run lots of coax to get to two different TV’s, one nearly 100’......great signal quality. In fact, the TV on the longest cable picks up more channels.

5 of 5 It did the trick! August 29, 2019
Reviewer: Mercer50 from Newington, CT  
Ordered an Omni Antenna and an Amplifier. As it turned out, all I needed was the Amplifier. Went from 22 channels to 35 channels.

Reviewer: David from New Hampshire  
Product seems to be well made, but I could see no change when it was installed.  In fact it seemed to work the same, whether power was supplied to it or not.  I removed it and went back to the passive splitter that I’ve been using for years.  Needless to say I’m disappointed.
