Just installed Dish Net on the boat. It's a 2002 Regal 3860. Problem is there are 3 TV's onboard and a line spliter somewhere. Everything works fine if I direct conect the coax to receiver, but not at the shore power station on the boat. I've looked behind the ac/dc control panel where I found the main coax coming in but no spliter. Has anyone ever worked with a Regal or similar crusier and come up with a possible solution of getting the cable to the salon Tv?
