4.0 ALIGNMENT TO SATELLITE
The 1.8 meter offset reflector contains a 22.3oelevation offset look angle.
Therefore, when the reflector aperture is perpendicular to the ground, the
antenna is actually looking 22.3oin elevation. The lower back rib on the reflector
is a Sight Reference Rib and can be used to read the correct elevation look
angle.
1) Aligning to primary satellite: Place the inclinometer on the sight reference
rib as shown in figure 3. This surface compensates for the 22.3ooffset in
the reflector, therefore a direct reading can be taken.
2) Raise or lower the antenna to find the desired elevation by turning the 5/8"
nuts located on the elevation channel. Position the top nut so that it will
not interfere with adjustment. Turn the bottom nut clockwise to increase
elevation and counterclockwise to decrease elevation.
3) After the correct elevation angle is set, rotate the antenna in azimuth by
loosening the six 1/2" set screws located on the canister and rotating the
reflector assembly about the mast pipe until the correct signal is found.
4) Peak the antenna signal by fine adjustments made in both azimuth and
elevation.
5) Tighten the four (6) 1/2" set screws in the canister.
6) Tighten all 5/8"hardware on the elevation adjustment rod and the reflector
support tube.

SECTION V MAINTENANCE
5.0 MAINTANANCE OVERVIEW
After installation, the antenna requires only periodic inspection. It is anticipated
that maintenance, if required, will be minimal and easily handled by a local or in-
house maintenance staff. The materials used in the construction of this Earth
Station Antenna virtually eliminate any maintenance repairs.
5.1 PERIODIC INSPECTION
It is suggested that a periodic inspection be performed at least every six months.
NOTE: After any very severe weather conditions, inspection of the antenna
should be performed to determine if foreign objects have caused damage or if
survival specifications have been exceeded.
This inspection should include the following:
1) Check all bolting locations - all bolts should be tight.
2) Check all structural members - repair or replace if damaged.
3) Check the foundation anchor bolts - they must be secure and with no
failure signs in foundation.
4) Check for corrosion - on the reflector structure and mount.
5.2 REFLECTOR
Prodelin's reflector does not require any maintenance. The composite
construction of the reflector is virtually impervious to any damages that could be
caused by weather or other atmospheric conditions.
It is only necessary to inspect for any physical damage done by vandalism or
very severe weather conditions.
Should any damage be detected to a portion of the reflector, contact the
Customer Service Department at Prodelin for recommendations involving
reflector repair.
