I had the Winegard AS 2000 automatic satellite dish on my Sovereign
for a few years until it would no longer lock on the satellites. According to Winegard this was caused by new satellites in the sky from Dish and Direct-TV that caused the AS 2000 to malfunction. The software in the AS 2000 could not identify these new satellites and would not lock on the old ones. I was eventually able to work out a deal with Winegard to replace the AS 2000 with their newer Traveler model. It works great.
According to Winegard not everyone with a AS 2000 system has the problem I had. It could be the part of the county they are located or quirks in the installed software. So, I still have the old AS 2000 and if anyone is stilling using this system some of the components may be of use to you. If so just PM me and I would be happy to donate them at no cost just pay for shipping.
