Orezok - Thanks. Is there a possible simpler solution such as: I ran 4 - RG6's from the dish to the 322 location when I built the house. Could I change the LNB to a quad (I have one) and just use 3 separate cables at that location (4th one to the 301 in a separate room? I also have a DP34...

I currently have a DP Plus LNB connected to a 301 (on one RG6 feed) and a 322 through a diplexer on a separate feed. I want to add a 508 at the 322 location (and keep the 322 operational), but can't figure out the proper wiring. I've searched the forums, no joy. Can anyone provide suggestions?
