The problem is that my HD TV is hooked to the HD dish, the three other receivers are still hooked to the other dish. I would have to run two cables from the dish and hook up the multiswitch.
I could do it, but I don't like heights.
Do you have your 4 feeds running down from the dish ?
If so, just place the MS at that point, then no need to go up to the dish.
