It is a very basic design and should work well. Be aware that it needs to be mounted on the side of the fuselage, not the floor or top and oriented so the coax is parallel to the longitudinal axis. I've used similar antennas for ham radio work for many years.

She works very well, very light ( full carbon), very strong and a beautiful look.

I now have a Dynon radio under the floor of the baggage bay so the coax will route up the back of the baggage bay to about half way, then run longitudinally mid-fuselage for about 18 inches at which point it will mount to the SA-006 antenna plate. So, yes, the antenna will be mounted vertically. I guess a portion of the coax will not be parallel to the longitudinal axis due to the radio location. I figured it was more important to have a short coax cable between the box and antenna. I would still like to know the theory on how it works though, "simple dipole antenna with the radiating elements folded back" doesn't help me visualize what is going on.
