Slide the 2" x 75" length of tubing (the end
with the insulators attached) through the upper
and lower plate of the top tower section as
shown in Figure 6. Do not tighten the U-bolts
Select the 2" x 51" section of tubing and slip the
drilled end over the swaged end, of the 2" x 75"
piece of tubing. Align the holes and secure with
the 1/4"-20 x 2 1/2" screw, nut and lockwasher
as shown in Figure 7.
Select the reducer clamps and install on the end
of the 2" tubing, using #10 x 1/2" screws, lock-
washers and nuts. Do not tighten at this time.
Carefully adjust the partially assembled vertical
radiator until you measure 90 1/2" from the top
edge of the top tower plate to the top edge of
the reducer clamp. Refer to Figure 7.
Position the two insulators on the 2" tubing as
shown in Figure 6, then tighten the U-bolts
evenly. The insulators must be positioned as
shown to properly insulate the tubing section
from the tower.
Slide the metal angles in the elongated holes to
position the tubing section until the tube is per-
fectly aligned with the axis of the tower.
Tighten the screws securely!
NOTE: You may wish to assemble the
remainder of the vertical radiator separately and
install on the antenna immediately before
raising the antenna to its vertical position. This
will avoid allowing the tubing to droop and
permanently "set" in this condition.
Select the 1 1/4" x 48" piece of tubing, mark at
9" from the end and slip it 9" into the 2" tube
assembled in the tower, so that 36 5/8" (93.02
cm) remain exposed above the reducer clamp.
See Figure 7.
Select a #16 tubing clamp and slip it over the
end of the 1 1/4" tube. Select the 1 1/8" x 38"
tube and insert it into the 1 1/4" tube so the
swaged end is 33 3/4" (85.72 cm) from the end
of the 1 1/4" tube. See Figure 7.
Select a #10 tubing clamp and slip it over the
end of the 1 1/8" tube. Refer to Figure 5A for
proper placement.
Select the 7/8" x 72" piece of tubing and slip
the unswaged end into the swaged end of the 1
1/8" tube. Measure 64 1/2" (163.8 cm) from the
end of the 1 1/8" tubing to the end of the 7/8"
tubing. Tighten the clamp. See Figure 7.
Slip a #6 tubing clamp over the end of the 7/8"
tubing. Tighten slightly.
Select the 5/8" x 48" piece of tubing and slip
the unswaged end into the 7/8" tubing. Measure
42" (106.7 cm) from the end of the 7/8" tube to
the end of the 5/8" tube. See Figure 7.
Slip
a #6 tubing clamp over the end of the 5/8"
tubing. Tighten slightly.
Select the 7/16" x 68" piece of tubing and slip it
into the 5/8" tube. Measure 66" (167.6 cm) from
the end of the 5/8" tube to the end of the 7/16"
tube. See Figure 7.
Check the overall dimension of the vertical
radiator. It should be 27'9 3/8" (3.47 m) from
the top of the upper tower plate to the end of the
radiator. If it is not, adjust the 7/16" tubing ac-
cordingly. Now tighten the compression clamps
securely.
Place a 7/16" caplug on the end of the vertical
radiator.
