I have an install date later this month for the VIP 622, and was told by the CSR that Dish would also be installing a Dish 1000 antenna. I am in the Wash, DC area and my current setup, about 4 years old, is two Dish 500 antennas (one pointed at 61.5), three single LNBFs, and a DP 34 switch. My receivers include a 942 (2 separate cable runs available all the way to the receiver), a 510 and a 508. Do I need a new antenna, and which version of Dish 1000 should I expect to get. Thanks.
