Step
To configure the antenna for operation on 15-40 Meters, attach each end of the Large
"Inner Loop" Antenna to the two terminal straps located on the Black Feed Line Box
5
using four screws and nuts as depicted in Figure 4 below. Set this assembled piece to the
side, for the moment.
Now, assemble the Outer Loop Antenna as depicted in Figure 4 below for 15-40 Meters
by first building two separate outer loop "semi-circles" consisting of:
 One long/curved outer loop element, fastened to one short/curved outer loop element,
6
fastened to one long/curved element.
 Use four screws and four nuts to (loosely) fasten the three antenna elements together.
 Repeat this process to assemble the second semi-circle.
This completes the partial assembly of the antenna for operation on 15-40 Meters.
7
Go to Step 12.
To configure the antenna for operation on 10-12 Meters, attach each end of the Small
"Inner Loop" Antenna as depicted in Figure 3 below to the two terminal straps located
8
on the Black Feed Line Box using four screws and nuts. Set this assembled piece to the
side, for the moment.
Now, assemble the Outer Loop Antenna for 10-12 Meters as depicted in Figure 3 below
by building two separate outer loop "semi-circles" consisting of:
9  One long/curved outer loop element, fastened to one short/curved outer loop element.
 Use two screws and two nuts to (loosely) fasten the two antenna elements together.
 Repeat this process to assemble the second semi-circle.
This completes the partial assembly of the antenna for operation on 10-12 Meters.
10
Go to Step 12.
Continue the final assembly steps for either the 15-40 Meter or 10-12 Meter antenna by
attaching the Black Feed Line Box to the top of the two antenna semi-circles and by
attaching the Grey Alpha Match Box to the bottom of the two antenna semi-circles as
follows:
 Lay the two semi-circle antenna elements on a flat surface. Form them in the shape of
a circle but do not connect the top or bottom ends of the semicircles together.
 Locate the Black Feed Line Box and place it at the top and inside of the newly formed
antenna "circle", with the box's SO-239 connector facing downward (towards the
11
center of the antenna circle). Connect one terminal strap of the Black Feed Line Box
to the top left element of the semi-circle. Connect the other terminal strap of the Black
Feed Line Box to the top right element of the semi-circle. Use four screws and nuts to
fasten.
 Locate the Grey Alpha Match Box and place it at the bottom and inside of the antenna
"circle", with the box's tripod receptacle facing downward. Connect one terminal
strap of the Alpha Match Box to the bottom left element of the semi-circle. Connect
the other terminal strap of the Alpha Match Box to the bottom right element of the
semi-circle. Use four screws and nuts to fasten.
