
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
