5 of 5 It Did The Job December 28, 2019
Reviewer: Steve from St. Augustine, Florida  
I was getting intermittent reception of some channels on the TVs at the ends of long runs of coax. This fixed that problem. I also pick up a couple more channels i didn't know were available.

4 of 5 Good. But pay attention to outputs October 15, 2019
Reviewer: John from Pinson, AL  
This distribution amplifier is pretty good. The Power IN and Antenna IN ports could be labeled better. Of the 4 distribution ports, you need to be careful if you have H-VHF channels. The left-most port on the bottom will cause the H-VHF channels to be blocked for some reason. I suppose it is because it passes power/signal in both directions. The other 3 ports on the bottom are purely OUTPUT signal sources. So for me, I had to go to plan "B" and put what would have been the 4th TV onto a separate antenna to get BACK the H-VHF signals. I worked with what I had. So I used a Stealth 50 Antenna with an Ultra Mini 1 and an antenna amplifier.
