Preparing for alignment
To prepare the antennas for alignment, proceed as follows at both link ends:
1
Using the instructions provided with the antenna, set the elevation and
azimuth adjustment mechanisms to the centre of the range.
2
Using the instructions provided with the antenna, adjust the position of the
antenna mounting bracket such that the antenna is pointing at the other end of
the link. Use a compass and the bearing provided by the planning report.
3
Once the antenna is in position, resecure the mounting bracket.
4
Connect a suitable voltmeter to the RSSI connector. Figure 8 shows the location
of this connector for the ODU and Figure 16 shows the connector on the IRFU.
Connect the center of the RSSI connector to the positive terminal of the
voltmeter.
5
Use the voltmeter to monitor the RSSI voltage during alignment.
