Receive pointing
Receive pointing peaks the receive signal. You must peak the 
signal even if the antenna is locked to it.
Use the installation software to check the signal strength. Then 
adjust the antenna to peak the signal. The installation software 
shows numerical and graphic indications of signal strength.
Adjusting azimuth Figure 41 illustrates how you adjust antenna azimuth by moving 
the antenna from side to side.   
To adjust the azimuth, follow these steps:
1. Stand behind the antenna, grasp the outer edges of the 
reflector and, while looking at the azimuth alignment mark, 
adjust the azimuth 1/8-in. toward the center pencil mark, 
mark 1.
2. Let go of the antenna and count slowly to 5 while reading the 
signal strength value from the OPI. 
Allow the IDU enough time to track and register the signal 
strength.   
3. If you are receiving a signal and the signal strength has 
 
 
If no signal is present and the azimuth alignment mark has

Note:
Make small adjustments (never more than 1/8 in. of 
azimuth as measured at the mast). Wait 5 sec between 
adjustments to give the IDU enough time to lock onto the 
satellite signal.
