Well, finally got my Silver Sensor and hooked it up last night. Was unhappy with an amplified Terk 25 which only provided me with one of the three current DTV stations broadcasting. I still can only receive PBS, and am unable to get UPN and ABC. Is this my last attempt at using an indoor antenna? Could both ABC and UPN be transmitting with less power? If I get PBS at 90% locked, and they are all on the same tower, you would think I should get all three?
