Chapter 2. Outdoor Installations
Installing the Antenna
3DB 23063 ADAA - Rev 004 July 2007
This chapter describes the following installation procedures:
• Installing the Antenna
• Installing the ODU
• Installing a Coupler
• Installing ODU Cables and Connectors
• Installing Lightning Surge Suppressors
• Weatherproofing
Antennas must be installed in accordance with the manufacturer's instructions.
• For direct-mounted ODUs the antenna includes a collar with integral
polarization rotator. Dependant on frequency band, these antennas are available
in diameters up to 1.8 m (6 ft).
• Where standard antennas are to be used, the ODU must be installed on a
remote-mount, and a flexible waveguide used to connect to its antenna.
Before going to the site, check that you have the required installation tools as
recommended by the antenna manufacturer, and that you have data for
positioning the antenna on the tower, its polarization and initial pointing.
• For direct-mounted ODUs, polarization is determined by the setting of the
polarization rotator.
• For standard antennas, polarization is determined by the orientation of the
antenna.
