  • Works perfectly from long distance
Style: 1-Port (Pre-Amp)
Brings in channels my antenna would not alone. I have a GE attic antenna and I am 45 miles from Atlanta. I could receive some channels and they would come and go. I installed this in the attic and connected to my antenna and get all the local channels now and perfectly clear! I have it set on high gain. Love it as i can now watch golf again! I am even able to watch nextgen channels i was unable to get prior. ... show more

  • absolutely fantastic preamp

  • works like a charm
Style: 2-Port
My house is about 45 miles from the local transmitters. My digital antenna would do OK with a couple of stations but a couple of others would come and go. Talked to the antenna company and they sent me a new antenna, that didn't do much. Seems like the signal needing boosting. Got this on a whim. Does exactly what I had hoped. Got the missing two networks. Would highly recommend ... show more

  • Works OK. Kinda sorta...
Style: 1-Port (Pre-Amp)
We live in a rural area with multiple transmitter towers between 30 and 50 miles away. We had one of those cheap plastic $30 outdoor antennas with the built-in amplifier and rotating motor. It worked great for about five years, and the motor conked out. So I thought I would upgrade to a bigger, all-aluminum antenna, and I wouldn't need the amplifier. Wrong. So then I bought this. Now we get all the same channels we used to, but no better than the $30 all-in-one solution that worked for years. Also, there is no "high-gain" function. LED on the amplifier is supposed to change from green to red when you switch to "high-gain" mode. When I throw the switch on the power splitter, LED stays green. And there's no change in the reception, for better or for worse. So this was all a very expensive experiment that netted me no better than my original cheap solution. UPDATE: Lowered my rating from 3 stars down to 1, for poor customer support. I contacted their customer support over the high-gain issue. I suggested it could just be a defective switch in the power splitter they supplied. They told me to bench test it with a short coax cable. I replied that's what I did before I decided to install it anyway. And I asked if they could just send me a replacement switch to try. They said, no, I needed to bench test it again with a short cable and send them a video of the light not changing to red. I told them that's too much work to climb up there (it is installed on the antenna mast, a few feet below the antenna, per their instructions), de-install their unit, bring it inside, and take a video of something that I already know...when they could very easily send me a replacement switch to try before I went to all that trouble. No follow-up. ... show more

  • Improved signal strength
Style: 2-Port
I bought this to help my clearstream antenna pick up more channels and improve its signal quality. I was initially getting 80+ channels without it but after installing it, I can get as much as 110 channels. It also reduced pixelation from the other channels. It also looks well built with quality.
