New to this forum but have been monitoring this great site for a while. I have got a Twin-Dual LNB Sat Dish and Basic Cable Feed(for local stations) running in to a Spaun 5x8 Multi-Switch. I have Diplexers at the TV locations where there are DSS recievers. Everything works great as I can watch Cable & Sat on all of the TVs. I just purchased a Mits WS-55711 TV and want to recieve OTA HD. I plan to purchase the new Sony HD200 set-top box for HDNET and HDHBO when it starts shipping. What I am wondering is can I somehow combine the CATV & OTA signals, run them through the Spaun Multiswitch and split it back out at the TV? If not, can I use my second coax run and feed the Mits OTA reception. If so, could I also split the OTA antenna signal and not lose signal strength so I can feed my other HDTV? Any Suggestions appreciated!!
