Install the lower tube 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 included, as shown in
Figure 3
. 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. 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.

Assembling the Vertical Sections
Assemble the vertical in an area that is flat and has sufficient room for the length of the antenna
during assembly. Lay the element tubing 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", and 1" with the slits in the element tubes toward the top of the
antenna (the 1" top element section does have slits but is installed with the slits downward). The
bottom element section you previously mounted in the base section is 36" long and all the other
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
