I have a Dish pro 1000. I plan on replacing it, too much rain fade with moderate rain and pixilatting on heavy cloudy conditions. I have coming a Dish 500 with twin legacy lnb's. I am using the old Voom dish right now for 129. When I want to put up the 500 for 110 and 119, do I use the Dish pro lnb's with it or the twin legacy lnb"s.
