During the installation process there are several references to the A-325 hardware ten- A-325 Tensioning sioning procedure. The A-325 hardware must be properly tensioned to avoid slippage between bolted surfaces under high loads. Slippage can cause the corresponding assembly to move, causing antenna misalignment. When designated, the A-325 hard- ware should be tightened according to the following tensioning procedure. Note: Tensioned bolts are for final connections only and should not be loosene

Tripod Mount The three-point mount in an elevation-over-azimuth configuration optimized for geosta- tionary satellite applications. The mount enables standard elevation ranges from 2°-62°, and 33°-90° with high-look strut configuration. Azimuth range is ±82°. Fine adjustment is provided in both azimuth and elevation. An example of the assembled tripod mount is provided in Figure 2. Figure 2 Before assembling the mount, verify that all parts are present. Follow the subsequent procedures for prope
