An A/B switch could be used for dual or more motorized dishes. As to the directions on
Sadoun's site, I really do not know how much simpler they could be. They say set the motor to the same as your latitude. Pretty straight forward. Even gives you the way to find your lat and long. As to setting the dish elevation it is x - declination. x being a magic number based on your motor. Declination is found in the chart provided.
Must start by pointing to your true south sat. That may not be explained as clearly but that sat is located at the same location as your longitude or the nearest one to it. Even tells you how to find true south. I found the instructs very easy to follow when I did my first install.
