Dish500 501 Rcvr & home network

[hoover2000]

I'm sure this has been covered somewhere so I appreciate the the opportunity to ask. I have a Dish 500 w/ twin LNBs & bulit in switches, a single 501 rcvr, and OTA antenna for local signals. Plan to add a second TV w/ sat & OTA reception & plan to diplex the two signals to the new addition. The bigger project is to bring signals (satellite & OTA) into a networking panel from Leviton and distribute. All wiring schematics seen so far for Dish 500 have individual wiring for each rcvr from sat dish. How can I bring signals from the dish to a central point & distribute to rcvrs as needed w/o an LNB and dedicated coax for each? Thx in advance!
