I have recently purchased a portable satellite dish. I have been told to set the dish to Azimuth (Mag) 68*E and Elevation 35*. Dishpointer says I must use the following: Azimuth (M) 82,3*E ? and elevation 36,1* My dish has no elevation scale and is also the 'offset' type how do I calculate the 'built-in' offset angle? to compensate on my inclinometer. My dish measurements are 380mm High x 350mm wide. In South Africa we use 68.5E Intelsat 10(IS-10) I Intelsat 7 (IS-7).
