Hope someone on this site could help? Been searching for weeks..... Approx 6 months ago I had swapped from Directv to Dish Network. Had a Hooper 3 installed with three wireless Joeys. The dish antenna has two LNB's looking at 61.5 and 72 with one cable coming from from dish to Hooper 3. No other switches, nodes, nothing. There is an extra cable coming from the dish but it is not hooked up where it enters the house. Looks like a spare cable. No connector on it. Here is the question? I have two Wally receivers in a RV parked next to the house. I want to connect these two receivers to the existing antenna. I have talked to many many folks, no one can agree on what is needed or if it can even be done? I have a travel antenna but don't want to set it up when at home. I do know based on my location, the wallys must hit eastern sats for local HD's, already figured this out. Can I connect to the extra cable coming from dish? Or do I need some type of switch? Thanks in advance for your help.
