Martin,
This is a simple dipole antenna with the radiating elements folded back to make
it more compact. 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.
Here is a link with more information:

I have some 44,45 - 1 3/4" 15/5PH or 46mm 17/4PH tolerance h11 if anyone would
like to make stainless pistons.

Hi
I replaced my warp drive by an e-props durandal 100 propeller. She works very well,
very light ( full carbon), very strong and a beautiful look.

Hi Jim, thanks.
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.
Regards,
Martin
