Measure Antenna Height

Antenna height refers to the vertical distance between the phase center and the ground.
Since the antenna height cannot be directly measured, it is automatically calculated by
SurPad software based on the measured height you input and measurement type you
select.
CAUTION: No matter what the value of measured height you input and what kind
of measurement type you select, the value of antenna height is unique.
The principle is as follows:
 h: the vertical height from the phase center to the ground.
 s: the slant height from the measuring line to the ground.
 a: the pole height, that is, the vertical height from the ground to the device bottom.
To measure antenna height, do one of the following:
 Set the measured height to the slant height and measurement type to slant height.
 Set the measured height to the pole height and measurement type to pole height.
The SurPad software automatically calculates the antenna height.
