1. Summary
The 1.2 m off-set satellite communication antenna is the leading production of
my corporation, which adopts of totally molding production, advanced

3
technology, superior manufacture, and with ascendant performance index. This
production has spacious market demand all the world. The antenna is mostly
composed of the pedestal mount, reflector, back support strut, elevation
adjusting lead screw, feed strut, feed bracket, feed OMT and so on. ( refer to
the figure ).
1.1 Pedestal mount
The antenna adopt the kingpost structure, which is composed of kingpost (φ76
steel tube), rib plate (used to fix the foundation),supporting parts in the
middle and basement in the top. The pedestal can be unloaded, installed simply
and carried conveniently.
Azimuth adjusting mechanism adopt double half- rotation and lock
structure .The center of the top of the pedestal mount is fixed by anchor
bolts ,which would be adjusted conveniently, locked reliably, and have strong
capability of wind-loading.
Elevation adjusting mechanism and locking mechanism are special and proper.
The locking mould is press into arc. In any elevation angle, the anchor nut can
stick flexibility to the locking mould ,which make it have the high adjusting and
locking character.
Compare with similar production, our pedestal mount has the high intensity,
stability, wind loading and adjusting capability.
1.2 The reflector of the antenna.
Main reflector with high precision ( σ≤0.4mm) adopt the high quality
anti-rust alloy aluminum which is stretch-formed once .The edge of the reflector
is rolled repetitious ,which enhances the strength of reflector ;The main
reflector adopting the square tube structure is fixed onto the rolling position
with the 2 pieces feed struts, which bears the accuracy of position and
convenience of installation, and can guarantee the electric capability completely.
To guarantee the strength of the whole reflector , the supporting
struts(adjustable up and down ) are install between the feed strut and
kingpost .Compare with the similar product ,the reflector bears high strength

4
and surface precision character.
1.3 Surface coating of antenna
The antenna as one unit using outdoor, the environmental condition is severe,
so the surface must be dealt with electrostatic spraying. The steel structure
dealing with dacromet bears anti-rust and long lifetime.

3. Operation and maintenance of antenna
3.1 Loosening the connecting bolts of feed clip slightly, adjust the feed
focus and polarization angle to the proper angle .
3.2 Loosening clip bolts of the half of the kingpost , rotate the bolts of elevation
lead screw up and down , elongate and shorten the length of elevation
lead screw to the angle coincident with the satellite’s , then, rotate the clip
bolts of half of kingpost .
3.3. Loosening the fastening bolts of bracket and kingpost, rotate azimuth to
the angle of the satellite needed.
3.4. According to the singles, re-adjust the azimuth, the elevation angle, the
position of feed and polarization angle continuously to gain the best signals.
At this time, pointing the satellite is successful , then , fasten all the loosen
bolts .
3.5. The antenna should be inspected and maintenance periodically after using,
which can guarantee the operation capability and prolong the lifetime.
3.6. Fastener should be inspected per 2 to 3 month in normal condition, Replace
promptly the fastener with the same specification if damaged or brush off.
Especially, before and after severe weather .
3.7. Surface coating should be inspected periodically , re-paint the damage
position promptly
3.8. After the severe weather, clear the accumulation of the antenna surface
( such as sand , dust , snow and so on )
