I have a DTV oval dish with a built-in multiswitch and four individuals runs into my house. At the end one of those runs I want to connect two DSS receivers (but can't afford to use two separate runs because I need them elsewhere). I've tried a 2 GHZ splitter, but as you probably know, this doesn't work very well, and at times, neither receiver can see the dish. Do I need a separate multiplexer or diplexer at the end of this run? I know this may have been answered in a thread somewhere, but I did some searches and couldn't come up with my exact scenario, so please bear with me if this has been answered. Thanks in advance for your help.
