Figure 8
The X9 boom to mast clamp is designed to be mounted on the
tower/mast so the built in boom shelf feature can be utilized. Following this
suggestion, if possible, will simplify antenna installation.
Reference Figure 8 for assembly of boom to mast clamp. Required
hardware is listed in the Boom to Mast Clamp Assembly Parts List. Form
the boom shelf by attaching the lower boom bracket (506) to the mast plate
(542). Attach mast plates (542 & 618) to mast using U-bolts (3209) and V-
blocks (35).
Place the boom on the boom shelf during installation. Loosely
attach the top boom bracket (506) to the mast-plate (542) and to the lower
boom bracket (506) as shown in Figure 8A. This allows the boom to be
moved back and forth for tower top element mounting.
When all elements are securely mounted to the boom and the
feed system is in place, line up the 2 holes in the top of the upper boom
bracket (506) holes with the corresponding 2 holes in boom section BC.
Insert bolts (588) and tighten in place. Next, tighten the 8 bolts, securing
the upper and lower boom brackets. Tighten the 4 bolts connecting the
upper boom bracket to the mast plate.
Attach good quality coax with a PL-259 connector to the X9
matching network. Route the coax as shown in Figure 7C. Form a drip-loop
with the coax and secure the coax to the boom. Insure PL-259 connector
is waterproofed with a good quality sealant after it is attached to the matching
network.
