6.
Align the fine azimuth axis. Use the hexagonal wrench to adjust the Azimuth
Fine Adjustment Screw (
). Be sure to sweep the complete range of the
azimuth in order to determine the maximum received signal strength position.
When the optimum axis is achieved, tighten both Azimuth Adjustment Lock Bolts
(
).
7.
Align the fine elevation axis. Use the hexagonal wrench to adjust the Elevation
Fine Adjustment Screw (
). Be sure to sweep the complete range of the
elevation in order to determine the maximum received signal strength position.
When the optimum axis is achieved, tighten both Elevation Adjustment Lock
Bolts (
).
8.
Perform Steps
6 and
7 for the remote ODU.
9.
Repeat Steps
6 and
7 for the local ODU.
10.
Use the DVM to verify maximum received signal strength on both local and
remote ODUs. For best performance, measured RSSI should be within ±4 dB of
the calculated value.
11.
Once the optimum position has been achieved for the ODU pair, tighten the
azimuth adjustment lock bolts (
) on one ODU, being very careful not to move
the ODU when tightening.
12.
Tightening the azimuth adjustment lock bolts will tilt the ODU, so realign the
elevation again for optimum position.
13.
Once the optimum position has been achieved for the ODU pair, tighten the
elevation adjustment lock bolts (
) on the ODU, being very careful not to move
the ODU when tightening.
14.
Repeat steps
11 through
13 for the second ODU.
15.
Use the DVM to verify that the received signal strength has not changed on
either the local or the remote ODU after final tightening of the brackets.
Antenna alignment is now complete.
