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.

Max-Gain Systems Fiberglass for your Hex Beam

By now I have posted several times about my new G3TXQ Broadband Hex Beam which came online in March 2010. I figure it is time to post a bit more on the materials I used for my version of the hex beam. Read more about the fine spreader kit from Max-Gain Systems.

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.
