Using the 36" base section tube, install the feedline 1/4-20 x 1" long bolt through the hole in the
tube from the inside, so the threads stick out.
Put on a 1/4" star washer, 1/4" flat washer, then a 1/4-20 nut. Tighten securely.
Add another 1/4" star washer, 1/4" flat washer and 1/4-20 nut, but do not tighten. The feedline from
the UNUN attaches to this hardware.
Figure 3
shows the completed feedpoint assembly.
Figure 3
Install the lower section to the insulated channel
using the two 2" x 3/8" U-Bolts, two saddle clamps,
four 3/8" flat washers, four 3/8" split washers, and
four 3/8" hex nuts as shown in
Figure 4
. The base
section tube should extend 1-3/4" beyond the bottom
of the U-bolt clamp.
The feedpoint hardware should be coming out on the
left side as you look at the lower section as shown in
Figure 4
.
When tightening, observe the split washers. When
they fully seat (flatten out), the clamp is tight enough.
Any clamp should be tightened evenly from side-to-
side with an equal amount of thread above each nut.
