I just hooked up the Terk TV42 to my DTC-100. This is the OTA antenna that clamps onto the dish. I hope I have it wired correctly. I am running from the output of the 4X4 multi-switcher to an input on the antenna. From the antenna, I run the cable (RG-6) into the house. At the rear of the IRD, I have a diplexer going into both antenna A, and SAT IN. I am getting a signal of low 90s on the 101 bird and low 70s on the 119 bird. For me, that is acceptable. Only after jiggling the antenna, do I get a signal on the local HD channels, only briefly (a second or two). But, for the most part, I don't get any signal from the locals (analog or digital) at all. I plugged my cable TV cable into Antenna B, and I don't get anything from there (yes, I have the cable bubble highlighted in the menu for) at all. Do I need another diplexer outside? Does anyone have this set up at all? Is Terk that bad an antenna?
