I was recently given a Dish with a DPPlus LNB on it. The dish is black with DishHD written on it. I plan on using this dish with a VIP211 receiver in my RV. The LNB has two coax cables coming from it. My question is, does’ the DPPlus have a built in switch and the two cables are for two receivers, or do I need to join the two cables with a switch to see all three satellites (110, 119, 129) on the 211? If all three sat signals are on both cables, do I need to put a terminator on the unused coax?
