. Now take the 1.0” x 30” piece of aluminum and place at a minimum 2 inches into the
long aluminum element (5’ x 1 1/8”). The end of the long (5’) piece used should be the
one without the hole drilled in it. See Figure 1.
[ ] 7.
A hose clamp should be placed around the 1 1/8” pipe to secure it in place. Tighten it
with the 5/16” nut driver.

. A minimum of 2 inches of the 9” x 1 1/8” pipe should be placed onto the 1.0” x 30” piece
of aluminum and secured with a hose clamp.

NOTE:
The length of tubing placed inside 1 1/8” tubing will determine the overall height of
the antenna.

Now the hollow fiberglass insulator should be placed approximately 3 1/2” into the 60” x
1 1/8” aluminum tubing. See Figure 2.

[ ] 10.
Place one of the hose clamps around the aluminum tubing and snug the clamp using a
5/16” nut driver . The center conductor of the coax will be connected to the antenna using
a solder lug placed under the clamp. Refer to figure 2.

Place one of the small plastic spoke caps from the parts bag onto the end of each of the
capacitance spokes.
[ ] 12.
Install the short 6/32” screws in the rings of the loading coil assemblies and place a 6/32”
nut on each screw. Place eight (8) of the 36” capacitance spokes into the eight holes on
the top rings of the loading coil assembly (60M). Then, tighten the screws until the spokes
are snug. Now you should be able to turn the coil assembly over and they should balance
on the long spokes. See Figure 3 and Figure 4.
