1. Check to see if the elevation reference and polarization 

settings are still at their previously set values (the values 
calculated by the installation software). If they are not, see 
Installing the Az/El cap onto the antenna on page 15 and 
follow the instructions to align the antenna to the correct 
values.

2. If you have not already done so, tighten the clamp nuts all the 

way; then loosen them just enough to move the antenna 
reflector from side to side to adjust the azimuth.
The clamp bolts should be as snug as possible, while still 
allowing the antenna reflector to be moved from side to side. 
See Figure 39.

3. Use a compass to determine the azimuth bearing specified by 

the installation software as follows:
a. Rotate the antenna reflector in azimuth (sideways) until the 

reflector is pointed at the magnetic bearing. Use a pencil to 
mark the location on the mast, and label this mark 1.

b. Mark the location on the Az/El cap above mark 1. This is 

the azimuth alignment mark. (See Figure 40.)

c. Make another mark on the mast 3/4-in. to the right of mark 

1 and label it 2. Make another mark on the mast

 

3/4-in. to the left of mark 1 and label it 3.

4. Stand behind the antenna and point the front of the reflector 

to the left of the estimated bearing to the satellite so the 
azimuth alignment mark lines up with mark 2.
