Aligning Single-Polarized Antennas
Determine the azimuth of the antenna according to the installation position and height of the antenna.
Adjust the elevation of the antenna to the horizontal position.
Connect a multimeter to the RSSI port on the ODU at the local end and measure the voltage value V
NOTE
The red line of the multimeter is connected to the pin, and the black line of the multimeter is connected
to the inner wall (ground pin).
Retain the remote antenna secure. Adjust the level adjustment screw. At the local end, rotate the antenna
widely in the horizontal direction.
a
If three signal peaks are tracked, adjust the azimuth of the antenna so that the received signal level (RSL)
reaches the peak value at position 2.
b
If two signal peaks are tracked, adjust the azimuth of the antenna to the middle of positions 4 and 5. Then,
adjust the elevation of the antenna so that the three signal peaks such as the signals on the line AA' can
appear. Adjust the antenna so that the RSL reaches the peak value at position 2.
c
If one signal peak is tracked, adjust the azimuth of the antenna to the middle of positions 6 and 7. Then,
adjust the elevation of the antenna so that the three signal peaks such as the signals on the line AA' can
appear. Adjust the antenna so that the RSL reaches the peak value at position 2.
