6 - BOOM TO MAST ASSEMBLY
Before installing the antenna on the mast, check all hardware and worm
clamps to insure they are tight. Install the antenna on the mast as shown
in Figure 6. Using U-bolts (404), lock washers (19), and hex nuts (18),
fasten the antenna to the mast. Place the connector boot (115) on the coax
cable before assembly. Apply silicone sealant (116) to the threads of the
matching network RF connector and tighten the cable to the matching
network. Do not apply silicone to the center conductor or dielectric of either
connector. Slide the boot over the connector. Place the coaxial cable over
the top of element #2 on the boom and run the cable down the mast to the
radio equipment.
