Install the lower element on to the insulated channel using the two 3/8" x 2" U-Bolts, two saddle
clamps, four flat washers, four split washers, and four nuts as shown in
Figure 1
. Use the outer
upper and lower holes of the channel. 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.
Base Section to Mounting Pipe
Attach the completed base section to your steel ground mounted pipe using the two
DXE-CAVS-1P
Saddle Clamps, as shown in
Figure 3
. Use two V-Bolts, two saddles, four nuts, four flat and four
split washers. 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 the nut. The standard 1-1/4" galvanized water pipe (with its approximate
1.7" OD) is just fine for this application and can usually be found at your local home building
supply store.

Assembling the Vertical Sections
Assemble the vertical elements in an area that is flat and has sufficient room for the length of the
antenna during assembly. Lay the elements out in descending diameter sizes of 1-7/8", 1-3/4", 1-
5/8", 1-1/2", 1-3/8", 1-1/4", 1-1/8", 1", 7/8", 3/4", 5/8", and 1/2" with the slits in the elements
toward the top of the antenna (the 1/2" section does not have slits). All the element sections are 36"
long.
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.
