In trying to find additional information regarding the motor and dish angle adjustments for a motorized dish system, I was looking through the motorized dish setup tutorial on Sadoun's website. While it appears as though the motor angle setting is simply equal to the latitude value of the installation location (can anyone verify if this is the case for SG2100 motors as well?), the dish elevation angle appears to vary based on the make and model of the motor being used in a dish setup. There is a specific equation to calculate the proper dish elevation angle for each make and model of motor, however all of these calculations have one factor in common--the "declination angle" which can be found on a provided chart. That said, here's my question. The declination angle for a particular location appears to be determined by using the latitude of the location, so am I correct in assuming that the "declination angles" on the table are completely different and not related in any way to magnetic declination values which are determined based on longitude? In other words, am I correct in assuming that the declination angles on the table (determined by latitude) and magnetic declination (determined by longitude) are two completely different measurements and figures? If this is the case, then what exactly is the declination angle on the table a measure of, and why then is it necessary to set the dish to an offset other than zero if the motor is already adjusted to a proper true south elevation?
