This a best pre-amplier I am using with a UHF antenna.
Without this amplifier I got only few channels also sometime nothing, now I am getting more than 25 channels and all of them are more than 50 miles away. My antenna is mounted only 8 feet above the ground and near the wall but under the roof. This is a good buy for me.
This amp is one of the best purchases I've made for a TV accessory so far! Plugging into one of my TV's USB ports allows this amp to turn off and on with the TV, and immediately after connecting the amp I was able to pick up 3 channels that I had not been able to pick up in months. Thanks for a great amp!
This amp surprised me - I replaced an old AC powered amp with this one that turns off and on from the USB TV port. It pulled in a couple of channels I haven't gotten in months!
