Aligning separate antennas
When using separate antennas at each site to achieve spatial diversity, one should be
mounted with Horizontal polarization and the other with Vertical polarization.
To align separate antennas, proceed as follows:
Procedure 6-29 Aligning separate antennas
1
At the Master and Slave units, connect the Horizontal polarization
antennas to the ODUs, but disconnect the Vertical polarization
antennas.
2 Align the Horizontal polarization antennas using the installation tones,
as described in
3
At the Master and Slave units, connect the Vertical polarization
antennas to the ODUs, but disconnect the Horizontal polarization
antennas.
4
Align the Vertical polarization antennas using the installation tones, as
described in
5
Re-connect the Horizontal polarization antennas. The tone pitch should
increase due to the additional received signal.
6 Weatherproof the antenna connections at the 'H' and 'V' interfaces of
the ODUs, as described in
29.
