- Wires measured to specifications are connected to measured tip spacers and form a single set
for each band. Each set consists of two 1/2 drivers and one reflector. There are two tip spacers for
each set. When connected all the pieces form a single set that is strung around the frame of the
beam.
- Insulated wire is used to provide protection in saltwater environments. The wires specified here
are pvc insulated and its characteristics are unique. Therefore, the specifications certainly will not
apply to bare copper wire and probably not to most other insulated wire either. Specifications for
this same wire but without insulation can be found on the Specifications and FAQ's page.

Finished product
Cut two 1/2 drivers and one reflector wire
using the measurements here for each
band. Carefully label them so they don't get
mixed up.
If you use bare wire, these measurements
will not be applicable. You should then use
the measurements on the specifications
page.

When strung on the frame
of spreader arms, each wire
set will look like this from

Using the Kevlar cord and
crimps, make a pair of these
for each band using the
lengths in the previous photo.
Lengths are between the
metal lugs on the ends.
Carefully label each pair so
as not to get them mixed up.
The lugs will be soldered to
the wires in the next step to
complete the wire set.

Solder a lug to one end of each
1/2 driver wire. Solder the other
end of each 1/2 driver wire to one
end of each Tip Spacer. Then
solder the other end of each Tip
spacer to the ends of the Reflector
wire. When the joints cool, slip the
heat shrink over the crimps and
with a hair dryer, match or other
heat source, shrink the shrink.
Repeat for each band, being
careful to label each one.
