Chapter 7 • Pointing the antenna

1037312-0001 Revision A

Setting azimuth

With the elevation and polarization set to the initial values given

by the installation software, follow these steps to set the antenna

azimuth to the initial value specified by the installation software

and then adjust it as necessary:

1. Use a compass to determine the azimuth bearing 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

⁄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.

You must allow the IDU enough time to track and register the

signal strength.

Loosen these three

nuts to rotate Az/El

assembly and reflector

from side to side.

Note: Make small adjustments (not more than

⁄8 inch of

azimuth as measured at the mast). Wait 5 sec between

adjustments to give the IDU enough time to lock onto the

satellite signal.
