I've had Dish for about 6 years now.It seems like every few months my connectors get corroded or the switch box goes bad from corrosion or something.I have a 811 and 1 other receiver upstairs.I called Dish and told them that I've had it with this and I'm ready to switch to Direct TV.They said they would send someone out at no charge.I have the old type dish with the switch box outside.Isn't there another dish with the switch box inside?If so,should I ask them to switch it out?Also,what else should I make sure they do while they're here?I'm sooo tired of losing my signal.Thanks,Pete
