I was all set for an install yesterday, but my fears quickly became true. I couldn't get installed because the subcontractor said that there were trees in the line of sight for at least one satellite. Is there a website that one can go to an put in one's address to see if I would be able to pick up any of Dish Network's 3 satellites? I really want more HD! I have 3 HD sets and only 8 HD channels.
