general lubricant between the aluminum tubing sections. Oils or general lubricants can cause
poor electrical connections for radio frequencies.
3. Clean the outside of the aluminum tubing to clear any dirt or foreign material that would cause
the clamps to malfunction during assembly.
4. The use of
DXE-P8A Penetrox A
is highly recommended. Penetrox A is an electrical joint
compound which effects a substantial electrical connection between metal parts such as
telescoping aluminum tubing or other antenna pieces. Using Penetrox A assures high
conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.
5. When assembling the aluminum tubing sections, ensure the area is clear of grass, dirt or other
foreign material that could cause problems during assembly of the closely fitted telescoping
sections.
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.
If you have
chosen to use
the optional
TB-4P
Tilt
Base, refer to
the
DXE-TB-
4P
manual. You
will be using a
smaller
mounting plate.
Using
Figure 1
,
attach the
mounting plate
to the back of
the insulated
Figure 1
channel using
four 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.
Locate the 36" base element section tube. The 18" tube is installed in the
36" tube aligning the feed through mounting holes. Install the feedpoint
hardware as shown in
Figure 2
.
