• Support cords from the center post to the ends of the spreaders along with two other cords
    between the ends and the middle of the two front spreaders establish and hold the shape of the
    hexagonal beam. When installed properly, very little tension is on the wires as these cords do the
    physical work

  • The cords are made of strong Kevlar with a UV resistant dacron cover and the hardware is
    corrosion resistant stainless steel and aluminum crimps.

Finished product
Measure out 7 cords of
Kevlar/Dacron with little "S"
hooks on the end. The
cords should be 128 inches
long, including the hooks.
The Kevlar is very strong
and will not stretch and the
Dacron covering provides
resistance to UV radiation.
Use the crimps instead of
knots.

You will need an
intermediate cord between
the two front spreaders.
Make this cord 89 inches
long but don't use hooks;
instead put a cable tie on
each end that will be used
to wrap around the spreader
at about the 15 M band.
Here is how the support cords are connected to the end of
the spreaders. Just hook down into the end and then secure
the hook with a large cable tie.

www.radioworks.com. Crimps are not necessary if you are
willing to tie knots instead, a perfectly suitable alternative.
Hooks can be obtained from local hardware outlets.
