There are parts made from fiberglass in this kit. Take normal precautions when handling any fiberglass material.
There may be fiberglass dust, slivers or particles present when the fiberglass parts were manufactured. The use of
typical fiberglass handling safety gear (gloves, dust mask, eye shield, clothing, etc.) when handling and working
with fiberglass is recommended. Use a damp rag to wipe the parts. Do not use compressed air to clean fiberglass
parts. Measures can be taken to reduce exposure after a person has come in contact with fiberglass. Eyes should
be flushed with water and any area of exposed skin should be washed with soap and warm water to remove
fibers. Clothing worn while working with fiberglass should be removed and washed separately from other
clothing. The washing machine should be rinsed thoroughly after the exposed clothing has been washed. Check
with your local or state safety and/or environmental agencies for more detailed precautions.
Center Post Assembly:
Assemble the one 1-1/4" OD x 58" long
fiberglass center post into the one 1-3/8" x 14"
long aluminum tube, slit end oriented toward
the middle of the center post. With the un-slit
end of the aluminum tube aligned flush with
the end of the fiberglass center post, secure
them together with the DXE-ECL-16SS
Element Clamp, over the slits, at 3/8" spacing
between the end of the slit end of the tube to
the element clamp as shown below.
Center Post Assembly
Spreader Assembly
Place one DXE-ECL-1000 on each slit end of the six 1" OD sections. Slide the 3/4" OD x 43" long sections
into the 1" sections approximately 3 to 4" and clamp them together. Ensure the slit ends are horizontally
aligned, not vertical. Position the element clamp
about 1/4" to 3/8" away from the end of the
section when tightening. The clamp tightening
screw should be on the bottom of the tube
assembly.
Place one DXE-ECL-0875 on each slit end of
the six 3/4" OD sections. Slide the 1/2" OD x 48"
long sections into the 3/4" OD sections
approximately 3 to 4" and clamp them together
as shown below. Position the element clamp
about 1/4" to 3/8" away from the end of the section when tightening. The clamp tightening screw should be
on the bottom of the tube assembly.
The six 3/4" x 5" long tubes are provided if you want to re-enforce the 1" OD sections when mounted to a
base or hub assembly. Refer to the DXE-HEXX-5TAP-2 Hexxagonal Beam 5-Band total package
instructions for details.

The six spreader rope connection assemblies are installed at the outside end of each of the 1/2" OD fiberglass
spreaders approximately 1/2" from the end as shown below.
Spreader Rope Connection Assembly
Center Post Rope Connection Assembly
The center post rope connection assembly is installed near the top of the center post and provides a superior
rope support connection hub to create the upward bow of the spreaders for the hex beam of your design. The
three 1/4-20 bolts are evenly tightened to hold the assembly on the vertical center post. Once tightened to the
post, the nuts are then tightened to secure the hex bolts in place. The ropes (6 pieces cut to length - plus some
extra for knots) are tied from the holes in the Center Post Connection Assembly to the ends of the six
spreaders through the P-Clamps. The Vinyl End Cap is installed at the top of the center post. This Center
Post Connection Assembly is the same high quality Center Post Connection Assembly used on the DX
Engineering HEXXAGONAL BEAM. The black vinyl cap is provided for installation at the top of the
center post.
This kit is provided for Amateur Radio Operator's
making their own design hexagonal beam or with
use on other commercially made hex style beams.
Therefore, the overlap and total length may vary
depending on the antenna design being used. You
may want to cut the fiberglass tubes to various
lengths depending on your design. As with all
amateur radio experiments, your results may vary.
If you plan on using these fiberglass spreaders with
the DX Engineering Hexxagonal Beam, please refer
to the instruction manual for the entire
HEXXAGONAL BEAM for more details.
