Ahhh...the X1 also supports 2 receivers from the VIP series...so I'm inferring that the PathwayX2 supports the one receiver you already have but the X1 doesn't. Is that correct?
I don't have any Dish service so am starting from scratch and Winegaurd makes it hard to compare their various products. I simple spread sheet or comparison function would be nice...but at least they make good products and stand behind them!
Good luck with the X2...it looks like the only difference for a newby like me is that it is larger on the downside...and gets a bit better reception in tougher conditions due to the size of the dish.
...and good luck with #3...we just launched #1 last week!
