I need some help with my motor please how do i calculate the elevation on my dish, on the sadoun website it say elevation for the SatcontrolSM3D12 is 46.5 minus declination i just want to know which declination, is it my latitude declination or the 46.5 declination i'm confuse. i live in Boston and my latitude is 42. Please help!
You're supposed to use that formula and lookup the declination angle based on your latitude.
so for boston latitude 42 it will be 46.5 - 6.49 = 40.01 so you should set your Dish elevation to about 40.
But let me tell you, last week i did a motor install and my calculated d.e. was about 8-9 degrees less then i had to put my dish to get accurate reception of the arc so you will have to experiment.
