Purcahsed a SWM and it works great. Only problem that I have is that my OTA signal seems to be affected when running through the switch. Have RG-59 cable with runs of approx. 75 feet or less to 2 HR-21's. When running only the OTA direct to my TV's, I receive digital signals for all local stations. When I try to run the OTA through the SWM with diplexer at the TV, I am able to get digital OTA signals for 1 or 2 channels and they tile. Is there anything that I can do to boost the OTA signal before or after entering the SWM that would not affect my DirecTV signal?
