Installation Procedures
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.
