I have a two dish install to do where the guy has 1 coax run to each dish which terminate in a utility room. The coax then needs to run to a R10 and two D10. I know the dvr needs two coax runs but how can I do this with only one coax run to each dish. I do have a Eagle Aspen MS44D switch. My question is can I use diplexors by the dish to convert two to one and then use them in the utility to convert back to two? Does this make sense? The coax was placed when the house was built and it would be very difficult to run more. Thanks for any help.
