• Adjusting the antenna azimuth and elevation

1037750-0001 Revision A

Adjusting the azimuth

To adjust the antenna azimuth:

1. Ensure that the three 5/16-inch azimuth lockdown nuts at the

bottom of the Az/El canister (shown in Figure 36) are loose
enough that the antenna assembly rotates freely on the mast.

2. Manually point the antenna reflector as accurately as possible

in the appropriate direction as indicated on the installation
reference sheet.

3. Tighten the three lockdown nuts just enough so that the

antenna does not rotate freely.

NOTICE

Do not attempt to adjust the azimuth manually by pulling on the
antenna reflector or feed support arm. Doing so could cause
permanent damage to the antenna.
