That may be the case for you
rserkes, but my HD dish is facing 180 degrees in the opposite direction of any trees on my property.
In fact, the closest tree that we were told to cut down is exactly 20' BEHIND the HD Dish. The second tree is 14' to the west of the first tree and 30' North-West of the new HD Dish..
Again, both trees are BEHIND the new HD Dish. There are NO trees within a 180 degree span (from Southeast to Southwest) of the dish. The new HD Dish is pointing somewhat Southwest as was the case with the previous two round dishes that are mounted to my eave..
Total incompetence...!
