If you are using the Slope Height Reading the antenna

height is calculated as follows:

Antenna Height =

√(√(

√(SR² - HO²) ± VO

If the Offset Point on the antenna is above the Mechanical

Reference Plane MRP, the Vertical Offset VO is negative.

The Slope Height Reading is measured from the point on

the ground to the outside edge of the antenna. The

Antenna used for this example is a Dorne Margolin T

(Leica AT504) as specified by the IGS. The Mechanical

Reference Plane will differ depending on the Antenna type

used.
