Step 1

Remove the two indicated strut-support setscrews, and attach the base angle to the cor- responding strut support using the supplied 1/2 inch clamping nuts and the previously removed strut-support setscrews as shown in Figure 3-22b.

Securely tighten the remaining mounting hardware to achieve the clamping force.

Follow directions for “Acquiring a Satellite”.

Repeat the entire procedure for the remaining strut assembly.

After the adjustments have been made, the manual actuator should be removed. The following steps provide the procedure for the proper removal of the manual actuator assembly.

Remove the manual actuator assembly by first removing the hardware securing the actuator to the base angle.

NOTE: The adjustment kit assembly should be removed after the antenna has been adjusted. Store the manual actuator assembly and the corresponding hardware in a dry area for future use.

Remove the remaining clamp segments with the corresponding hardware.

After the antenna is pointed at the satellite, tighten all azimuth and elevation setscrews to 35 foot-pounds.

If you are assembling a motorizable pedestal mount (P/N 208800) follow the directions for ground mount assembly before beginning this section. The following steps provide the procedure for assembling the motorizable pedestal ground mount.

Bolt the azimuth pivot assembly (top and bottom) brackets to the ground mount assem- bly using 5/8 inch hardware (hex bolt, flatwasher and hex nut) as shown in Figure 3-23.
