Azimuth 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.
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" in relation to the theoretical horizon, in order to position it precisely for the desired satellite.
Polarization is the tilt of the dish on the skew axis, and is also expressed in terms of degrees. This is the angle by which the dish must be "skewed" or rotated circularly to the change the angle of the attenuator arm, in order to position it precisely for the desired satellite(s).
