i just noticed on a post from the person from maryland with a sg2100, you told him his motor elevation is 51deg and dish elevation 24deg...i am now confused! i live in central california and you gave me similar specs except 53deg for motor elevation and dish elevation 24deg.. how can that be when we are so far apart on lat and long...mine is long-120.61154 and lat 37.398019...but you are the expert so i will believe you..
