    Solved my intermittent cable TV garbling

    This solved my problem of intermittent signal garbling while watching TV. A standard coaxial amplifier would not work because digital cable TV, and cable internet requires 2 way communication. This fit the bill nicely. It was either buy this $35 device, or pay somebody to run a higher quality cable from the junction box outside, to the wall outlet in my house.

    My splitter that comcast installed in the attic failed because of the heat. I bought this one and so far so good. Works just fine.

    I bought this amplifier to try to fix a connection issue at home. Internet works but goes away and then comes back every once in a while, so I installed this amplifier and it really does what it's supposed to do, but unfortunately it didn't fix my problem. I believe a coax cable needs to be replaced. Nothing to do with this amplifier though. I had to return it.

    Needed something to amplify the antenna signal to all 5 tvs in my house and this worked so well. I had to do some work to weather proof it but it wasn't a big issue.

    Without the power amplifier I received only 12 channels from my HD antenna. When I installed the amplifier I received 32 channels. Hard to complain about that.

    We wanted to connect our living room TV that is hooked up to the cable box to our bedroom TV so we could get cable TV channels in the bedroom as well. The reception on our bedroom TV is so much clearer now, which was an added bonus to just having the cable available in another room. Very happy with this

    Normal splitter had limited number of tv channels on scanning. This amplifier splitter brought in many more channels upon rescanning.
