Assembling the Vertical Sections
Note: JTL-12555 Jet-Lube
™
SS-30 Anti-Oxidant should be used between all antenna
element sections. Jet-Lube
™
SS-30 is an electrical joint compound to affect a
substantial electrical connection between metal parts such as aluminum tubing or
other antenna pieces. It ensures high conductivity at all voltage levels by displacing
moisture and preventing corrosion or oxidation.
Jet-Lube
™
SS-30 should also be used on all element clamps and stainless steel
threaded hardware to provide good electrical contact, prevent galling, allow easier
disassembly and to ensure proper tightening.
Assemble the vertical sections in an area that is flat and has sufficient room for the length of the
antenna during assembly. Lay the tubing out in descending OD sizes. Orient the slits in the tubes
toward the top of the antenna. The bottom 2.125" (2-1/8”) OD base section has slits on one end and
the feedpoint connection hole at the bottom end. All the sections are 36" long.
Each tubing section is inserted 4" into the next larger tube. Assembly is easier if the overlaps in the
tubing sections are pre-marked. A dark color felt-tip marker works well. Measure and mark 4" from
the end of each tube without the slit using a marker so it will be clearly visible.

Refer to Figure 10 for element clamp sizes and locations. Slide the clamps over each section
before putting them together. Align the clamps on each section facing the same direction. For final
assembly, all the clamps should be positioned very close to the top of each section and the body of
the clamp should be positioned between the slits as shown in Figure 8.
