Aligning antennas
Aligning separate antennas for spatial diversity
If a connectorized ODU is installed at either site with two separate antennas for spatial
diversity, proceed as follows:
1
Connect the horizontal polarization antenna to the ODU, disconnect the vertical
polarization antenna, and then perform
2
Connect the vertical polarization antenna to the ODU, disconnect the horizontal
polarization antenna, and then perform
3
Re-connect the horizontal polarization antennas. The received signal level should
increase.
4
Weatherproof the antenna connections at the 'H' and 'V' interfaces of the ODUs,
as described in
Monitoring received signal level
The goal of antenna alignment is to find the center of the main beam. This is done by
adjusting the antennas while monitoring the receive signal level. Choose one of two
methods for monitoring receive signal level:
•
Antenna alignment tones
•
Graphical alignment
