Setting the azimuth
Once you have set the elevation and tilt angle to their initial
values, perform the following procedure to set the azimuth to its
initial value as specified by the installation software, and adjust it
as necessary:
To adjust the antenna azimuth:
1. Use a compass to determine the azimuth bearing as specified
by the installation software.
2. Prepare to make azimuth adjustments as follows:
a. Fully loosen the three canister nuts shown in Figure 52.
b. Tighten the top nut only, just enough so you cannot rotate
the Az/El assembly around the mast.
c. Loosen the top nut incrementally until you can rotate the
Az/El assembly by holding and moving it.
3. Stand behind the antenna, grasp the antenna reflector bracket
(not the reflector), and rotate the antenna assembly about the
mast until the reflector is pointed in the approximate azimuth
heading.
4. Adjust the azimuth to the right about
1
/
8
inch.
5. Let go of the reflector bracket and count slowly to 5 while
reading the signal strength value from the OPI or computer.

NOTICE
Do
not
attempt to adjust the azimuth manually by pulling on the
antenna reflector or feed support arm. This could cause
permanent damage to the antenna.
Loosen these three
nuts to rotate Az/El
assembly and reflector
from side to side.
