I just purchased a used motorhome with a crankup Winegard satellite dish on the roof. The previous owner used it with a DirectTV receiver. Can I use my Dish VIP211 receiver with this antenna? Am I correct in assuming the antenna will receive either Dish or DirecTV depending on the proper receiver and aimed at the proper satellite. I believe I should try to aim it at the 119 satellite. I live in NE Ohio. Thanks for your help and I apologize for not being very savvy with all this technology!!
