I am considering to get Dish Network for the first time. My HD locals are on the eastern arc. I have looked at the angles and it apprears that the 1000.4 dish could be located on the side of my deck. This is my preferred location. I really do not want it on the roof. My question is when the installer comes how much control do I have to make him mount it on the side of the deck? Also, can he refuse to to mount it to the deck, and if so what could I do about it?
