I just setup my OTA antenna today, my antenna setup is Channel Master 4228( 8 bowties) with Winegard preamp. My STB is Sony HD300. The PBS(17.1) came in great with signal strength between normal and good. The problem is the CBS(4.1). When the signal strength is high the screen is highly pixelated and not watchable. But with the signal is between bad and good, borderlining poor, the picture is OK. What is the problem here? I thought this should be the other way around. Any suggestions will be greatly appreciated. BTW, I can't get NBC at all. I though NBC has good HD.
