Did the installer actually install the dish and look at the signal strength or did he just look around and say there was no line of sight? When I got my 500 upgrade last month the installer said I couldn't get 110 because of trees and that the signal meter he used said the signal was too low. After we looked at the 110 signal strength on the Point Dish Screen on the receiver the signal was in the 90's and was high enough. So much for the installer saying I couldn't get 110
