1 Presented By Andy Kunik AE8J

2  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

3

4  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

5  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

6  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

7  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

8  U bolts can crush fiberglass  Coax exposed to elements  Uses hose clamps and tie wraps  Wire clamps hard to adjust

9  Center hub and aluminum clamps

10  Manufacturing Drawings

12  Wire Spacer made from PVC plastic

13

14  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

15  Easy access to antenna  Telescoping or tilt over  Minimum height 30 ft.  No guy wires  Rohn 25g  House (roof) bracket  Tilt over base section  Winch and pulley system
