Fine Adjustment. Attach fine adjustment assembly between adjacent elevation strut sections as shown in Figure 50 using appropriate brackets, U-bolts, brass hex nuts, flat- washers and threaded rod. Securely tighten all adjustment assembly hardware.

Note: Adjustment assembly may also be attached in alternate position shown depend- ing on required elevation angle.

Attach fine adjustment assembly between adjacent azimuth strut sections as shown in Figure 51 using appropriate brackets, U-bolts, brass hex nuts, flatwashers and threaded rod. Securely tighten all adjustment assembly hardware.

Note: Fine adjustment assembly on azimuth strut should be positioned away from ground mount angles.

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 to 50-60ft-lbsand 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 support installation section for instructions on assembling and attaching the feed support assembly to the reflector.
