Appendix: Measuring antenna heights

AT502 Pole
If you are using the antenna on a

pole select the antenna type AT502

Pole (or AT501 Pole) during the

begin of a survey. The Vertical Height

Reading (VR) per default is 2m.

Normally you do not have to change

this value. The Vertical Offset (VO) is

0m and is applied automatically.

AT502 Tripod
If you are using the antenna on a

tripod together with the height hook

select the antenna type AT502 Tripod

(or AT501 Tripod) during the begin of

a survey. Measure and enter the

Vertical Height Reading (VR). The

Vertical Offset (VO) is 0.360m and is

applied automatically.

AT502 Pillar
If you are using the antenna on a

pillar or a tripod without height hook

select the antenna type AT502 Pillar

(or AT501 Pillar) during the begin of a

survey. Measure and enter the

Vertical Height Reading (VR) from

the pillar benchmark to the

Mechanical Reference Plane (MRP).

The MRP is the underside of the

threaded metal insert at the bottom of

the antenna housing.
