Hughes AN6-098P Manuale Utente

 

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 

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. 
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 

1

⁄

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.
