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
