What I've learned (correct me if I'm wrong Bill): My 322 receiver is a Dish Pro Plus (DPP) compatible receiver. DPP allows me to feed 2 receivers with a single cable coming from the dish. However, the dish LNB must be DPP compatible as well. Mine is not :(
I'll need a second cable going into the camper if I want to watch 2 TVs using the dish and receiver I have. If I'm pulling a second cable, using the existing cable as a pull cord, I might as well pull RG-6. I need to buy some to run to the dish anyway.
It seems my options are:
1) Buy a DPP LNB and mast for my old dish and hope I can get it to work
2) Buy a new dish with the proper DPP LNB
3) Run a second cable into the camper to connect to the TV2 input on the receiver. Connect a second cable from the dish to this new cable.
4) Replace receiver with Hopper/Joey (Don't know if my dish is compatible)
5) Do nothing and be happy with sat on 1 TV
I'm OK with #5 but I'm going to try #3
