Classic Traffie Style Hex Beam Antenna Simulation

This is a simulation of the M W style hex beam sold by several vendors and inspired by Traffie. This single band example was designed and simulated for 10 meters. The M element is driven at the midpoint by a sine wave at about 28.3 MHz. The W element is the parasitic reflector.

The first 50 seconds show the magnetic magnitude H. The simulation restarts at about 51 seconds to reveal the same run, but with the electric field E shown. Both the magnetic and electric simulations have exactly the same sine wave stimulus.

In both the H and E simulations you can clearly see how the fields build first in the driver then the reflector. Once the fields have stabilized after ten or so oscillations, the driver and reflector work together to launch EM waves in the direction of the driver.

If you ever wondered how a hex beam, or any compressed Yagi-Uda, works, here is your window into Maxwell's equations.

Enjoy.

Some explanation of what we're seeing would sure help.
