I was looking for an 5 or 6 bands antenna, reliable, small-scale and relatively efficient, when I discovered the Hexbeam. After a few days of research, I decided to build the G3TXQ version. Steve Hunt (G3TXQ) bring great improvements to the classic version of the Hexbeam :

  1. -better SWR

  2. -wider bandwidth

  3. -gain more linear

   I will not reinvent the theory, so I prefer to guide you towards the websites that help me in this project :

  1. -G3TXQ : All what you need to understand the Hexbeam.

  2. -K4KIO : All what you need to build the Hexbeam.

  3. -HB9MCZ : The secret of the aluminium center post.

  4. -KG4JJH : Amazing work.


   The Hexbeam is easy to build, but some details have to be respected for the general quality of the antenna. There is the most important things to me :

  1. -Base plate must be strong enough to resist to the spreaders movements.

  2. -With the help of a small cove, add a little angle at the base of spreaders: less stress on the spreaders and better spacing between the wires 10, 12 and 15m.

  3. -In order to obtain an impedance of about 50 Ohms, you have to respect a formula between the two tubes of your aluminium central post. See diagrams and formulas below, for air dielectric only.






Z = 136,7 x LOG (0,9259 x A/B)

Z = 138 x LOG (1,07 x A/B)



Z = 138 x LOG (A/B)

   After have been mounted over one year in French Guiana, I could say : the objective is complete. The climate is very hard for antennas, but apart a raptor attack, I never had any mecanical problem. For the price it’s a very good value.

   The Front/Back ratio is according to the theory, SWR and bandwidth are great. I do not many runs, I’m looking principally for DX and after over 2000 contacts my number of DXCC is about 185. For sure, it’s not a big gun antenna, but for using 100 watts and this small-scale antenna, it seems to work very well.
