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.

4 of 5 Better than expected October 15, 2019
Reviewer: Mike from Partlow Va  
Due to unforeseen circumstances received item later than both parties expected. I live in the deep neck of the woods with stations no less than 35miles away with surrounding trees blocking/weakening signals  The connection had to be placed under the modular home as that's where all the cables are and no power outlets. With its ability to receive pwr through the first line the Ultra Mini exceeded my expectations by still boosting weak signals with power connected through the first port bringing in various channels from areas I didn't expect.

5 of 5 Works great October 15, 2019
Reviewer: Dave M from Holley NY.  
I highly recomend this .
I have 4 TV,s running off a single antenna .
I had 2 that had great pictures and 2 that only picked up a couple channels.
I did some research , and decided to go with CM, because thats the brand antenna i have.

Great choice.!
It took only 15 minutes to hook it up.
Re scanned all my tv,s. And all4 have the same amount of quality pictures .
