Coarse azimuth adjustment
Make coarse azimuth adjustment as follows:
1.
Loosen the three Az/El canister nuts shown in
Figure 23
enough to allow the
antenna assembly to rotate freely on the mast.
Figure 23: Az/El canister nuts
2.
Holding the reflector bracket, point the antenna reflector as accurately as
possible in the direction indicated in OASIS or on the installation reference
sheet.
3.
Lock down the Az/El canister by fully tightening the three canister nuts.
Fine azimuth adjustment
For fine azimuth adjustment, use the azimuth adjustment bolt:
1.
Ensure the Az/El canister nuts are tight enough to prevent the antenna from
rotating on the mast.
2.
Using a
1
/
2
inch wrench, rotate the azimuth adjustment bolt shown in
Figure 22
on page 40 in either direction to achieve the desired azimuth angle.
Do not pull on the antenna reflector or feed support arm to make pointing
adjustments. Doing so could cause permanent damage to the antenna.
Instead, use the adjustment mechanisms and procedures described in
this chapter.
3.
When the azimuth is set as desired, tighten the four azimuth lockdown nuts
under the azimuth base.
