● The downtilt angle varies over the horizontal beamwidth. Patterns
measured ±90° from the center of the beam have decreasing
tilt angle until there is no tilt 90° from the main beam.
● The horizontal half-power beam width increases with greater
● The resulting gain reduction depends on azimuth direction.
● There is uniform downtilt over the whole azimuth range.
● The horizontal half-power beamwidth is independent of the
● There is identical gain reduction in all azimuth directions.
