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.
