- 5 -
assemblies, backing plate, 12 stainless steel clamps, black vinyl cap and stainless steel hardware.
Carefully un-box the antenna and separate the various parts. All of the element sections are 36"
long. Nested inside the 36" drilled base element section is the 18" drilled section for added wall
strength to the base element section. The vinyl cap for the top element section should be installed
after assembly of the vertical is complete.
Note:
DXE-P8A Penetrox A Anti-Oxidant
should be used between all antenna element
sections. Penetrox is an electrical joint compound to affect a substantial electrical
connection between metal parts such as telescoping aluminum tubing or other antenna
pieces. It ensures high conductivity at all voltage levels by displacing moisture and
preventing corrosion or oxidation.
UMI-81343 Never-Seez
or
DXE-NSBT8 Anti-Seize
should be used on all clamps, bolts
and stainless steel threaded hardware to prevent galling and to ensure proper
tightening.
Vertical Base Section
The base section is made up of an insulated mounting channel, an aluminum mount plate and the
base antenna section which is 36" long, with a hole drilled at one end. Nested inside the base
antenna section is an 18" piece of tubing with a hole drilled at one end, to add wall strength to the
base section and the feed point hardware is pre-installed.
If you have chosen to use the optional
DXE-TB-4P
Tilt Base, refer to Appendix B. You will use a
smaller mounting plate with the
DXE-TB-4P
Tilt Base kit.
Using
Figure 1
, attach the
aluminum mount plate to the
back of the insulated channel
using four each of the 2" bolts,
eight flat washers, four spacers,
four split washers, and four nuts.
Tighten firmly, but not enough
to crush the insulated channel.
The spacers are required when
the optional Tilt Base is
installed. They are being
installed as shown on this plate
to act as a washer and for safe
keeping.
Figure 1
Locate the 36" base-section tube. Install the 18" section inside the
36" section aligning the drilled feedpoint hardware holes. Install the
feedpoint hardware (1 " hex head bolt, two star washers, two flat
washers, and two hex head nuts) as shown in
Figure 2
.
