his site provides guidelines to build a G3TXQ broad band hexagonal beam R.F. antenna for
the six amateur radio bands, 20, 17, 15, 12, 10 and 6 meters. This antenna is featured in the
March 2009 edition of QST magazine and is a significant improvement over the Hex-Beam
The hexagonal beam offers a number of features as follows:
- Gain and front/back comparable to a two element yagi.
- Six bands with low SWR
- Broad band characteristics
- Low weight and low wind load
- Construction from general hardware components
- Ease of adjustment
If you have been to other sites on construction of the hexagonal beam you might be a bit confused.
You see, some sites tell you how to build the “original” hexagonal beam which is patterned after the
design of the HEX-BEAM, a trade marked product of Traffie Technologies. The wires for this original
design for a single band look from above, like an “M” over a “W”.
This original design is a good antenna and owners of the HEX-BEAM are quite vocal about its
performance as were builders of the homebrew version. I used to be one of the homebrew
builders and was so enthusiastic that I published a set of guidelines like these to help others
But, things have progressed a little and thanks to the exhaustive work of Steve Hunt, G3TXQ, a
slightly different configuration of the hexagonal beam has been discovered. Viewed from above
the wires for a single bander look like the sketch to the right.
Which one is better? Well, owners of the original HEX-BEAM are very loyal. But the only
competitors in the market are selling only the new broad band hexagonal beam and
homebrewers are all building that version of the hexagonal beam instead of the original. And
here is the reason why.
