I'd rather not buy another dish network dish and I was wondering if it would hurt or is it compatible to use my current FTA dish 36 inch with a Dish Network receiver. Will it hurt hooking the receiver via the cable that runs to the HH motor? Which satellites are on the Eastern Arc? I see most of the channels I would like to subscribe to are on 72.7w. Are the LNB the same Ku? or do I need a Ka lnb. My cable company is never gonna go HD apparently.
