ALL AZIMUTH READINGS AND CALCULATIONS ARE BASED ON TRUE NORTH VALUES
The Antenna Azimuth is the direction that the antenna is pointing (only for directional antennas, not omni antennas). In most cases you will be using a spectral antenna.
For example: Say you are using three identical 120° sectors on one Tower Site. For maximum coverage you have them point at 0°, 120° and 240°. These three sectors will create overlapping 360° coverage from your tower site. To get the most accurate coverage area results, you should create a coverage map for each of the three sectors. The difference between the coverage maps for these sectors will be the Antenna Azimuths (0°, 120° and 240°).
