I am trying to get the elevation of my dish set correctly. I have a Hot Dish 90 that I am trying to mount on a SG2100 motor. I have the motor latitude set at 34, which is my latitude. When I go to dishpointer.com and look in the instruction book it tells me that for a SG2100 motorized system that I need to have the dish elevation set at 24.5 degrees. The problem is, the elevation scale on the Hot Dish 90 only goes down to about 25, from the best I can tell, and I can't get that low because of the bolt. What I am doing wrong? Does anyone have any ideas? I have posted some pictures below.
