I've been throwing the idea around about getting an FTA receiver and adding it to my current setup. I have the Dish 1000 dish and an OTA antenna with a motorized rotator that was all installed by me and that equipment I own. My Dish receiver (vip611) I do not own and am still under Dish contract. What would be involved in adding a FTA receiver? Would I need an additional dish or can I use my current dish where it's pointed with both my Dish VIP611 and FTA receiver using it.
