Ralph, good question. I wish I knew. But on the up side, I just got done putting a line for satellite to both the LR and Br. So I know it can be done. I hope you are referring to a line to two receivers. I traced the RG-6, I should say chased the RG-6, front to back, and never did figure out why they did what they did when wiring the coach. Well that's behind me now. So.............what I did was a little re wiring. I am not sure how the new ones are wired, but I cut one white GR-6 cable that comes from, I think a splitter in the rear, and goes to the bedroom. That cable can be found behind the bulkhead in a plastic wire loom that goes to the front. I then put a new connector on the end that heads toward the front and put a barrel connector on it. I then ran a peace of RG-6 to the UDC and disconected a cable that was not being used. Wala, satellite to both tv's. Or, if you are going to watch the same program on both tv's, look in the cabinet where your DVD player is. There may be a jack there. I believe that one goes to the bedroom. I attached a couple of pics, of what I did. I don't know if they will help you or not
Peace
Dave
