I had a reception problem with a pretty "no signal" pixilated or chains with a stressful noise. The worst was during the days of rain and I ended up with 3 channels! I wanted an amplifier for a single TV having found nothing else (especially highly rated) so I used me as an output. When you first try it does not do much, I have screwed the bottom adjusting screw and it does not market better. Leaving it plugged into the wall outlet I unplugged the antenna son and I have reconnected and the miracle it worked, it is necessary that it heats ?? Maybe, at least now it works great I capture all the channels with even a deterioration rainy days but nothing like before!
Update 02.09.2014 one week after posting my review it started messing over receipt back to square one! After allowing disconnected for a few hours it returned!?! Since I unplug it regularly kidding, I reconnect ... In short, a star less there must be better anyway!
