I have tried for weeks to keep my Ku Band Satellite Dish still. 36" Fortec Star on a pole with DG-280 motor and Fortec Star Dynamic Receiver. My Long/Lat is 81.4/40.8 degrees..If I get 72 degrees set , 83 degrees goes out of kilter..I cant keep a signal on any Sat location for long..Is there a way I can find a midpoint Satellite that will allow for all the sats to be in line?
