I see there are signal combiners/diplexers for OTA Antennas and SAT Dish that you can split behind your box to get both signals on the same line. I have DTV and would like to use the AM21 Tuner with my HR22 DVR in one room, and on my other HDTV also have the antenna signal using only 1 line split to the TV. Currently I have a Slimline dish with a SL3 SWM 3 lnb to one line coming from the Dish. The line is then split by an 8-way SWS-8WB Diplexer 2-2150 (to four DirecTV Tuners -2 HD where I want the OTA). If I were to combine the antenna signal before the splitter, would that give me OTA signal at all four TV outlets or would there be a problem for the SAT putting that combiner before the splitter? I'm not sure if I'm clear here but if anyone has done this of knows about the technical issues involved, I'd appreciate any feedback. Why am I doing this? I'm in CT and would like to integrate CT locals into my televisions. I can get the OTA signal but for DTV I'm a NY DMA.
