Lay the assembled feedline tubes above the
boom with the support insulators in the correct
positions. Attach the support clamps with the
appropriate hardware as shown in Figure 9-11
Detail A. The feedline tubes should be centered
on top of the boom, except where they go around
the boom-tomast brackets. Allow a 3/4" gap
between the closest feedline tube and the boom-
to-mast brackets. Tighten all hardware securely.
Beta Tube Assembly
Select the two 3/4" x 18" Beta Tubes, support
clamps, insulators, shorting clamps and hardware
and assemble to the bottom side of the boom as
shown in Figure 11. Use the 5/16" diameter
spacers to prevent crushing the tubing where the
pigtail wires attach. Tighten all hardware
securely. This assembly provides a D.C. ground
to the feedline and helps to match the antenna in
the 13 - 14 MHz range.
