Azimuth (Magnetic): is the angle relating to the horizontal positioning of the dish. The angle is expressed in terms of degrees, with North = 0 degrees, South = 180 degrees. Use your compass to aim dish at that angle.
Elevation: is the angle above the horizon, and is also expressed in terms of degrees. This is the angle by which the dish must be "tilted Up or Down" in relation to the theoretical horizon, in order to position it precisely for the desired satellite.
LNBF Skew: It is important to adjust the LNBF skew for stationary dishes.
