The gauge that comes with the dish is not accurate, with the inaccuracy differing from dish to dish.
With an inaccurate starting point, an adjustment must be made after the strongest signal is first obtained.
Start by setting the elevation gauge on the dish to 34° and the stand’s elevation gauge to the elevation for the local zip code.
Fine tune the elevation of the dish by adjusting the threaded legs on the stand. Stop when the strongest signal is obtained. Check the level on the side mast.
The degree of the bubble from off center will indicate the amount of adjustment, plus or minus, needed to the dish’s gauge.
Adjust the Dish’s Gauge by 1 or 2 degrees at a time, reseting the legs so that the bubble in the level is centered. Repeat this step until the strongest signal is reached and the legs do not need any more adjustment.
Now an accurate elevation can always be set. The dish’s elevation gauge can be locked and the elevation from now on will be set by using the mast’s elevation gauge.
