1027145–0001 Revision E 4–22 Installing ODUs Hub installation
At this point, the mount is tightened to the mast and the antenna is
tightened to the mount. If necessary, you can fine–adjust the
azimuth and elevation using the built–in adjusters shown in figure
4-18.

1. Use a compass or protractor to determine if the antenna
azimuth needs to be fine–adjusted.
Note: Accurate azimuth adjustment is especially important
for the 22.5° HT antenna. (Sectors are smaller and must be
set up precisely to achieve correct coverage.)
2. If azimuth adjustment is necessary, use a wrench to slowly
rotate the fine azimuth adjuster (shown in figure 4-18) until
the azimuth is set correctly.
1. Use the inclinometer to determine if the antenna elevation
needs to be fine–adjusted.
2. If elevation adjustment is necessary, use a wrench to slowly
rotate the fine elevation adjuster (shown in figure 4-18)
until the elevation is set correctly.
1. When both azimuth and elevation are adjusted
correctly, tighten the azimuth and elevation locking nuts
(figure 4-17) to 16 foot–pounds (21.7 Newton–meters)
torque.
At this point, antenna installation is complete, and the
antenna is aligned. Section 4.10 explains how to attach the
transceiver to the antenna.
