I have had it with DirecTV and Dish network and am ready to switch to Starchoice. The problem is I have 3 Dish/DirecTV mounts on my roof already and would really like to not put up any more. So my question is could I just take off a DirecTV dish and put a Starchoice dish on top of the mount and be OK? I want whatever dish Starchoice uses for HD. Thanks for any advice.
