Identify the Azimuth Range
First, you need to determine the necessary azimuth range for the
tracking avoidance zone(s). You will need to enter, in clockwise order,
the beginning and ending azimuths that define the outer boundaries of
the zone, relative to the antenna's forward arrow, which should be
pointing toward the bow.
NOTE: Each tracking avoidance zone must span at least 5º. Therefore, be sure
to set beginning and ending azimuths at least 5º apart.
