Connecting and Aligning ODUs / Antennas

Connecting and Aligning ODUs / Antennas
You perform antenna alignment using the ODU's audible tone.
To speed up the installation time, alignment of a RADWIN 2000 system
should be performed by two teams simultaneously, at site A and at site B.
To align ODUs with integrated antennas or external bipolar antennas:
1. For external bipolar antennas: Using a coax cable with N-Type connec-
2. For external bipolar antennas: Using a coax cable with N-Type connec-
3. Ensure that power is connected to the IDUs at both sites.
4. Ensure normal operation of the IDUs by the LED indications on the front
5. Direct the antenna of site B in the direction of site A. This is simplified if
When aligning the antennas, do not stand in front of a live antenna.

6. Make a horizontal sweep of 180 degrees with the site A antenna so that
7. Slowly turn the site A antenna back towards the position of site B, listen-
