BTW, I forgot to comment on your calculation above.
The "Fixed dish angle" specified in the
STAB documentation refers to the elevation of a sat to your south. For someone at a 28 deg latitude, this would be 57.3 deg. So your calculation above SHOULD be :
57.3-(45-28)= 57.3-17=40.3
Ie STAB is also using the approximation of using the declination of a southerly sat. I'm not sure where you got the "52" , but you can see that the 57.3 -(-28) is equal to 57.3 + 28= 85.3 ie = 90-declination.
It took me a while to figure out exactly what that crazy equation was doing.
