## Hexbeam Gets a Spine

My G3TXQ Hexbeam gets a new metal backbone to accommodate a VHF beam antenna. A byproduct is a much stronger antenna assembly than the common Hexbeam approach.

## Simulations of Classic & Broadband Hexbeam – The Movie

Many folks have successfully modeled all versions of the Hex Beam. Most of the simulation attempts use NEC programs.

Despite being a popular and productive way of simulating amateur radio antennas, another method of electromagnetic simulation makes use of the Finite-Difference Time Domain (FDTD) method.

Without going into too many details, the method divides up the simulation space into little cubes of volume. Then the next magnetic field values are derived from the current electric fields. Then the next electric field values are derived from the current magnetic fields. Repeat.

FDTD makes use of Maxwell’s equations to calculate the above fields. Being a Time Domain method, what follows shows a movie like display of what is happening in the antennas in super slow motion.

## Field Day Prep

Well Field Day 2010 all started to come together pretty well. I put all the drinks and heavy items in the front to ensure good positive tongue weight. Pre-positioned the radio on that beautiful desk. Loaded up several antennas. Three masts plus stakes, etc. I even managed to figure out how to get my hex beam in there with a minimum of dis-assembly. It is quite a mess. I am sooo glad I selected that slinky wire that does not kink.

Here is a picture.

## 5 HF Band Hex Beam on Six Meters

I am preparing for the Virginia QSO Party and want to add an alternative 20 meter solution for my 43 foot vertical plus get better 15 and 10 meter coverage; I have been working plenty of 15 meter contacts with the 43 foot vertical so I know that band is open. Plus you never know if the sunspots might give us some 10 meter fun too ðŸ˜‰

So…

I have been eagerly absorbing all there is to know about the hex beam style of HF antennas.

If you are the least bit interested in building or buying your own hex beam a must read web site is the G3TXQ study of the hex beam…

## Hexagonal (Hex) Beam Battle

It seems the hexagonal beam has come of age as multiple manufacturers square off in an attempt to claim market share of the growing market for this style of antenna.

Ever since the 2009 QST article many folks, myself included, became aware of the simple elegance of the Hexagonal Beam (also known as Hexbeam generally and Hex-Beam® by Traffie Technology).
