My Dish 500 was recently upgraded to a Dish 1000 (3 LNBs) for satellites 110, 119, and 129 as I upgraded my receivers from a Dish 811 to a ViP211 and a ViP222. I've noticed that some contributors to this forum make note of having a Dish 1000+ or a Dish 1000.2. What's the difference and how would I tell what version of the Dish 1000 antenna I got (the installer didn't leave any copies of the paperwork for my order)?
