Figure 3-14: The illustration below is an exaggerated cross section of a beam to e xemplify a horizontal
RSL level voltage reading against relative locations with an assumed fine tuned ver tical position.

the main beam and side lobes
1st Side lobe reading is typically
~20dB down from the main
beam

A represents the desired Magnitude
of RSL Voltag, notice there are three
clear high points. One should detect
all three points and "back-off" to the
high point.
5) Locking Down Radio Antenna
a) After the target RSL level has been achieved, ensure all bolts are tightened
evenly, securely and ensure the RSL voltage remains unchanged after tightening
is completed.
b) The very narrow beamwidth of this antenna (0.9º) makes it necessary to
completely tighten the bolts of the azimuth adjustment while adjusting the
elevation and vice versa.
