NOTE: The X9 is shipped with NOALOX® conductive lubricant and an applicator brush. Apply small amounts of
the lubricant to telescoping tubing sections during element and boom assembly. Apply small amounts of lubricant
to bolt/U-bolt threads to prevent galling (seizing) of the nuts during assembly. Also, apply small amounts to the
feedstrap assembly and matching network connections.
Figures 1, 2, 3 and 4 show the steps for boom assembly. Identify the tubing
sections, element brackets and hardware required for this step by using the
Boom Subassembly Parts List. Note the element brackets for Elements #3, #6,
#7 and #8 join the boom sections (Figure 3).
Refer to Figures 4A, 4B, 4C and 4D to assemble element brackets. The
1/4” hex nuts (85) are used as spacers on all brackets. Tighten these nuts in
place before assembling element bracket halves. The 1/4” flat washers (1/8”
thick) (529) are used on brackets as spacers (Figures 4A, 4B, 4C). The Boom
may be placed on a flat surface with all brackets laying flat on the surface. This
will allow all brackets to be fastened in line with each other. When tightening
the hardware, refer to Figure 4A and tighten all bracket hardware in this order.
Do not tighten the bolts on the Tuning Tube Support Insulator Bracket (Figure
4D). Allow the bracket to remain loose on the boom for Step 5 (Feed System
Assembly).
Nylon insert lock nuts are designed for one-time use. Do not tighten these
nuts if you expect to disassemble antenna sections during antenna mounting.
After mounting boom end caps (26), drill a small hole (1/4”) in the bottom
edge of the cap for water drainage. Determine which edge of the end cap will
be on the ground facing side of the boom when antenna is mounted in its final
position.
