Hughes BGAN Remote Antenna Installation Manual page 9

Step 8: Connecting the Hughes 9201 BGAN Terminal
Refer to the Hughes 9201 Terminal User Guide for instructions to connect a Personal Computer or Mac to the
terminal.
Step 9: Pointing the BGAN Remote Antenna.
For optimum performance, the remote antenna must be accurately pointed at the satellite. The instructions in this
section explain how to mechanically adjust the antennas' elevation and azimuth angles. These adjustments are
required for pointing.
Important Notes:
•
To aid pointing the antenna, refer to the Hughes 9201 Terminal User Guide on how to put the terminal in
antenna pointing mode.
•
The terminal must be powered ON for pointing.
•
The GPS fix needs to be obtained prior to connecting to the antenna as explained in step 7.
•
The BGAN Terminal needs to be left registered on the network otherwise a new GPS fix may be required.
•
The Hughes 9201 may need to acquire a new GPS fix if it has been switched off for more than 42 days. In
this case it must be disconnected from the external antenna and placed in a location with good visibility of
the GPS satellite constellation to obtain a GPS fix. Note: Hughes 9201 software version 3.8.0.3 and
newer incorporates a Loss of Acquisition (LOA) timer that allows the 42 day time limit to be extended
indefinitely as long as you register with the network at least once within the rolling 42 day period.
To adjust elevation, refer to Figure 10:
1. Loosen the two bolts in the curved slots on the terminal bracket.
2. Read the elevation angle from the elevation scale on the terminal bracket, using the red edge on the
pole collar as the angle indicator. View this edge through the curved slot on the terminal bracket.
3. Pivot the antenna to obtain the desired elevation.

To adjust azimuth, refer to Figure 11:
4. Loosen the two bolts on the pole collar.
5. Move the terminal to either side, in small increments, as necessary.
When you have maximized the signal quality, as instructed in the User Guide:
6. Tighten the two bolts in the curved slots on the terminal bracket to lock down the elevation adjustment.
7. Be careful not to change the terminal's orientation while tightening the bolts.
8. Tighten the two bolts on the pole collar to lock down the azimuth adjustment.
9. Make sure all other fasteners on both brackets are tight.
