OK so Dish shows up and I ask them to move my 61.5 dish to the roof, rather than give me a 1000. They get on the roof and tell me there is a tree blocking 129? I am in ATL and my Dish 500 has no issues with 110 and 119, but they say 129 is much lower and a distant tree will block the signal. Needless they won't move my dish. Is there some info somewhere on where exactly 129 is in relation to where my 110/119 dish is pointed?
