The “Hex Beam” or Hexagonal Beam is a two
element, directional, wire antenna.


It can be configured as a monoband or
multiband antenna


Can be designed for


up to six bands


Mostly practical for



20 meters and above








Six bands low SWR 20, 17, 15, 12, 10 and 6 Meters


Broadband characteristics


No antenna tuner required


No loading coils or traps


Light weight…. 25 lbs.


Low wind load…. < 5 sq. ft.


Single coax feed


Can handle full power


Gain and F/B ratio comparable to a 2 element
yagi


Better than 6
dBi

gain


Performs well at low heights…. 30 ft.


Small turning radius…. 11 ft.


Easy to build


There are two versions of the Hexagonal Beam


The classic Hex Beam by
Traffie

Technologies


And the G3TXQ Broadband Hex Beam









Classic Hex Beam



Broadband Hex Beam


The original Hex Beam was developed by
Mike
Traffie

N1HXA


Smaller
turning radius…. 9
ft.


Rather narrow band


Sold as a kit $1,129 for 5 band array


Developed by Steve Hunt G3TXQ


More Broadband


Slightly better gain and F/B ratio


Slightly larger turning radius…11 ft.


Sold as a kit by DX Engineering… $600 for 5 band array


Hexagonal Beam Antennas by NA4RR $450 for 6 band array


U bolts can crush fiberglass


Coax exposed to elements


Uses hose clamps and tie wraps


Wire clamps hard to adjust



Center hub and aluminum clamps


Manufacturing Drawings


Wire Spacer made from PVC plastic



Center hub all aluminum with compression clamps


Spreaders are telescoping fiberglass glued with marine epoxy


Coax runs inside center support mast


Stainless Steel hardware


Dacron tip spacers


14 Ga. insulated wire


Wire spacers are PVC


Easy access to antenna


Telescoping or tilt over


Minimum height 30 ft.


No guy wires
