Installing ODUs 6–15
RT installation
To adjust the antenna azimuth (horizontal pointing direction), you
move the antenna to the left or right, as illustrated in figure 6-13.
You adjust the azimuth until the antenna is pointed at the HT.

You adjust the antenna azimuth in three stages:
1. Coarse adjustment, using only the built–in antenna
boresight (steps 1 through 4, on page 6–16)
2. Finer adjustment, using the boresight and azimuth adjuster
tool (section 6.14)—after you attach the transceiver, ground
cable, and IFL cable.
3. Electronic pointing, using a voltmeter and integrated system
software (section 7.4). This procedure, a part of the RT
commissioning process, refines the azimuth adjustment to
point the antenna as accurately as possible.
