Installing the Base Station Outdoor Unit (ODU) 4-7
Azimuth Alignment 1. As needed, use a ratchet wrench and a 7/16-inch socket to
loosen the azimuth alignment bolt (7 in Figure 4-1).
2. Verify the mounting bracket is aligned with the correct azimuth
according to your site design plan.
Note If necessary, consult an USGS geographic map to identify distinctive
landmarks to get a precise bearing.
3. Point the base station ODU in the appropriate azimuth direc-
tion.
Note A compass may not give an accurate reading because of nearby metallic
objects or surfaces.
4. After the antenna is properly pointed, tighten the alignment
bolt until the ODU is secure, taking care not to over tighten it.
Note While fastening the mounting clamps, ensure the mounting bracket
remains aligned with the correct azimuth according to the site design
plan.
5. Verify that the antenna direction has not changed.
Elevation Alignment 1. As needed, loosen the elevation alignment bolt using a 7/16-
inch ratchet wrench.
2. Using a level, set the base station ODU at the proper elevation
angle.
3. After the antenna is properly pointed, tighten the alignment
bolt.
Redundant ODU
Installation
To protect against both ODU and cable failure, cable and install a
second (redundant) ODU separately from the primary unit. Such
ODUs are installed in the same manner as the primary ODU.
Note For redundancy, a second ODU is required for each sector of one or
more primary ODUs.
