Hi just set up my old dish brackets n pole are spot on dish in line with pole dish facing south picking up thor np realy strong signal astra 28,2 np 19.2 good but when i want o get 39 degrees helsat dish wont move enough to get to position,moved the dish and re did thor still coming up short is it all to do with having to keep moving the dish more off of its south axis? Thnx in advance.
