Thanks to the TC we made the leap from $atellite to OTA and Hulu (soon to branch out to Netflix). So far, we're lovin' it...except for one station. At first our local NBC station reception was great. But in the past month it has gone crazy! The signal fades in and out constantly - which is really annoying especially during Sunday Night Football and a handful of other shows not available via Hulu and Netflix We have researched - confirmed - tested - aligned - realigned the outdoor antenna but nothing seems to make this station reception any better. We are using a ClearStream4 HD Antenna. Should we try a pre-amp? I am very confused about the specifications of pre-amps that I see. Does anyone have a brand or model recommendation? Thanks in advance for the TC help!
