You should be able to sweep roughly 60 degrees to the east and the west of your true south location (longitude). I ran a 76cm dish from 87 and it swept from 30 in the east to 123 in the west (had a physical obstruction that would not permit any farther western travel) with reasonably good success. I say reasonable as now I have a 90cm and the difference is night and day. Worth every penny of the extra $20.00 purchase price. I gave my 76cm to a neighbor and aligned it stationary on G10R.
