Andrew 3.7-Meter Earth Station Antenna manual Seam Bolt Insertions

Step 3

Step 4

Insert all of the joint-plate bolts, except for the socket-head shoulder bolts. All bolts should be inserted from the same direction using a 5/16 inch hardware—flat washer under a lock washer and nut. DO NOT TIGHTEN.

Note: DO NOT force bolts—manipulate reflector halves to allow free insertion.

At both antenna seams, loosely install three location bolts and nuts (5/16 inch hardware) adjacent to the center hole as shown in Figure 3-32.

NOTE: The installer positioned under the reflector should insert the bolts from the underside, while the second installer inserts the flat washers under lock washers and nuts from the outside.
