A: I am using this with an antenna mounted in the attic. I was getting some weak signal depending on time of day, weather, etc. The coax run is about 60 feet. Adding this amplifier improved the signal. But read on... I did a little experimenting when I first hooked it up (about 2 months ago). At first I installed the amplifier close to the tv end of the coax. It did not make the reception better. Then I installed it in the coax line close to the antenna. THAT made the signal stronger. And in doing a little more research with a friend, he tells me that what he has read is that you need the amplifier as close to the antenna as possible, especially if there is a long length of coax between the antenna and the tv. My situation proved that to be true. But they don't really mention that in the instructions. The problem in my case was to get a/c power to an outlet in the attic. To test it, for several weeks I had an extension cord run up through the attic hatch. I have since run a permanent romex wire and receptacle. I must say that this amplifier DID improve my signal. I would recommend.
Q: Will this amplifier work with an over-the-air HD TV antenna
A: I attempted to boost the signal for one TV and the reception was as bad or worse than before.
