18.1
Holding and panning the directional
antenna properly
Proper use of the antenna is a major factor in obtaining reliable
measurement results. Correctly holding the antenna and panning it (turning
it about the directional axis or azimuth) prevents inaccuracies in the
measurement and achieves reproducible results.
18.1.1 Proper holding
There is a position sensor built in to the antenna handle as well as the
electronic compass. The sensor measures the elevation angle and the
polarization angle of the antenna. While the elevation and polarization can
provide important information for determining the direction of the signal
source when taking bearings manually (Manual Bearing), the elevation and
polarization angles need to be kept constant during panning when
performing a Horizontal Scan. The polarization and elevation angles should
be as close to 0° as possible.

a = azimuth
b = polarization
c = elevation
