tubes toward the top of the antenna. The bottom 2-1/8" element section has slits at both ends. All
the element sections are 72" long.
Each element section is inserted 4" into the next larger element. 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 element without the slit using a marker so it will be clearly visible. Mark
the 8" long 1-3/8" OD tube at 4" (middle) as well. Mark the 36" long element attached to the tilt
base section 4" from the top. The next element should never be above this mark.
Locate the hardware pack containing element clamps. Slide all the clamps over each element
section (as shown in
Figure 11
) 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 element clamp screws on each element
section to face the same direction. At final assembly, body
of the element clamp should be positioned between the slits
in the elements and 1/8" from the edge of each element as
shown in
Figure 9
.

Using
Figure 10
and
Figure 11
for dimensions, assemble the 1-1/2" element sections with slits at
both ends to the 1-1/2" element section with slits in one end using the smaller 1-3/8" OD 8" tube.
Insert the 8" tube 4" (as marked) into the slit ends of both top element section 1-1/2" elements and
tighten the clamps.
Making sure dirt or grass does not adhere to the element sections to be joined, insert the marked end
of the 2" element into the 2-1/8" bottom element until the 4 inch mark on the 2" element is even
with the top of the larger element section. Position one of the larger clamps at the very end, but not
hanging over the edge.
Make sure the body of the clamp is positioned between the slits and tighten securely.
Repeat the procedure with the marked end of the 1-7/8" element and the 2" element.
Continue mating the smaller elements inside the larger ones. Double-check the vertical element
sections you have just assembled. When completely assembled (including the base element) the
antenna should measure 43 ft. overall as shown in
Figure 11
.
