Adjust the elevation adjustment screw. At the local end, gently adjust the elevation and azimuth until the
RSL reaches the peak within the tracked range.
Repeat Steps 3 to 4 to ensure that three signal peaks are tracked in both horizontal and vertical directions.
When the local RSL reaches the maximum peak value, tighten the local antenna.
Adjust the remote antenna to ensure that the RSL at the local end and the RSL at the remote end reach
the peak value. Check the status of the ODU indicator on the IF board. The ODU indicator on the IF board
is off. If the ODU indicator on the IF board is yellow and blinks every 300 ms, continue aligning the
antenna.
Tighten all the screws of the antennas after the alignment is completed.

Aligning Dual-Polarized Antennas
NOTE
If an OMT is used to connect the ODUs to the antenna in direct-mounting mode, align the antenna in the same
method as that for aligning single-polarized antennas. If soft waveguides are used to connect the ODUs to the
antenna in separate-mounting mode, follow the procedure to align the antenna:
Power off the vertically polarized ODUs at both
ends of a radio link, power on the horizontally
polarized ODUs at both ends of the radio link. This
ensures that the antennas at both ends transmit
horizontally polarized signals.
Adjust the azimuth and elevation of the antennas
at both ends by referring to the description in
"Aligning Single-Polarized Antennas", and ensure
that the main lobes of the horizontally polarized
signals are aligned with the antennas.
