Right now I have one DishPro 500 twin LNB dish on my roof. It is pointed to DN and only brings in those sats. I will be adding shortly a second DishPro 500 twin LNB to my roof to bring in Bev. Will a Diseqc 4 X 1 switch be the only switch I need to hook up the second dish? It came with my Pansat 2700A. Or will I need the DP44 switch?
