So I just finally upgraded to a Hopper3 from my 722. The First tech, last week, could not go up on roof because of snow, so had to reschedule. The tech that came out this week informed me they would not be able to go on my roof because of safety rules from dish. He installed a third dish on my roof(near the edge). Very disappointing as I built access into the chimney when I built the house just for dish install which now can't be used. Now I am left with a bunch of dish scrap left on my roof, including three mounts and two dish's, that I will have to find someone else to remove.
