I have had my OTA setup going for about 2 weeks now and have some channel 2 issues. The picture looks good, but pixelizes quite a bit and "sometimes" freezes. When it was installed, I was getting 20 DB on the installers meter for Channel 2. I have no problems with any other channel. I have a Samsung T151 OTA decoder with a Winegard 7042 with a Winegard pre-amp. The antenna is on my roof (2 story). I am about 45 miles out in Lake in the Hills. Any suggestions?
