Installation Procedures
Set fine elevation and azimuth strut positions by loosening strut set screws and selected
out fine adjustment hex nut. Turn corresponding inner hex nut in appropriate direction
until required strut length is achieved. Securely tighten strut set screws and correspond-
ing outer hex nut.
During final electrical tuning, adjust elevation and azimuth struts appropriately to length-
en or shorten struts for optimal signal strength.
After fine adjustments are complete, ensure strut set screws are securely tightened and
spray with zinc-rich paint. Securely tighten hex nuts and U-bolts on both elevation and
azimuth fine adjustment assemblies.
Securely tighten eight U-bolts on elevation pivot assembly and upper and lower azimuth
axis joints.
Remove both fine adjustment assemblies and store in weather protected location for
future use.
You have now finished aiming your antenna at the desired satellite. Proceed to the Feed
Installation instructions packaged with the feed assembly for information on assembling
and attaching the feed assembly to the reflector.
By now, you can see that your installation of the 4.5-Meter Earth Station Antenna is
almost complete. The feed system is the last phase of the base installation described in
this manual.
Note: All antenna options (such as feeds, shields, anti-icing, etc.) possess installation
instructions within the individual kits contained in the shipment.
Attach feed struts to 222930 feed support as shown in Figure 78.
