[QUOTE="Robbo, post: 551707, member: 256551"] The declination angle for your lat is 7.96 by my quick calculations. Your dish offset angle is 22.6 degrees.(you said) Thus the angle between the axis of rotation (the swivelly bit:)) and the plate on the back of the dish will be 22.6 +7.96=30.566 degrees. The dish offset is added as you need to add to the declination, the dish offset angle, to account for the fact the the dish is pointing up the air, when the back plate is vertical. You would set the dish as above. Then send to your nearest due south satellite (19.2), then tweak the dish, and swivel the polar mount around the main pole for max signal. To move the dish to 19.E, you would work out the difference between your longitude and the satellite's polar position. Once that is all done, you should be tracking the arc fairly well, ready to move the dish around to 28E. Adjustment should only be done at the apex of the arc. [/QUOTE]
