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 as
shown in
Figure 11
.
Each element section is inserted into the next element section. Assembly is easier if the overlaps in
the tubing sections are pre-marked. A dark color felt-tip marker works well. Measure and mark
from the end of each tube without the slit using a marker so it will be clearly visible.
Locate the hardware pack containing element clamps. Refer to
Figure 12
for element clamp sizes and placement. Slide all the
clamps over each element section before putting them together.
You can lightly tighten the element clamps just below the slits in
each element section to hold them until needed. Align the clamp
screws on each section to face the same direction. At final
assembly, body of the clamp should be positioned between the slits
in the tubes and 1/8" from the edge of each tube as shown in
Figure 10
.

Using
Figure 11
and
Figure 12
for dimensions, assemble the 40/30 Vertical Antenna making sure
dirt or grass does not adhere to the element sections to be joined Double-check the vertical sections
you have just assembled. They should measure 29 feet and 2 inches overall. This overall height was
determined to be the optimum length during the engineering testing. There is adequate overlap that
will allow you to adjust the length as needed for your particular installation. Refer to the tuning
section of this manual.
