Check diameter setting bands to ensure they are uniformly taut. If not, check leveling of temporary supports and make necessary adjustments by adding or subtracting shims until bands are uniformly taut.

Begin A-325 hardware tensioning sequence (see page 12) with tee plates (P/N 202447) and rib connecting plates (P/N 202444). Next tighten support angle (P/N 49436) con- nections. Tighten the pivot brackets and elevation axis bracket last.

Remove diameter setting bands leaving corresponding edge joining plates (P/N 49294) installed using existing hardware.

You have now completed the assembly of the back structure and its attachment to the reflector. Proceed to the next section for instructions on mounting the reflector to the tri- pod ground mount assembly.

This reflector can be installed on the mount manually or by using a crane. However, Andrew recommends that this procedure be performed using a crane.

The following steps provide the procedure for installing the reflector to the mount using a crane.

Ensure all connections on reflector and back structure are tight.

Wrap crane straps around support angle between pivot brackets as illustrated by Figure 67.
