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.

Figure 41: Adjusting azimuth
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
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.
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.
3.If you are receiving a signal and the signal strength has changed, go to Peaking the signal on page 38, step 1.
If no signal is present and the azimuth alignment mark has
