I wrestled with a transponder antenna for my fabric covered motorglider. I
did not want an external antenna, but needed vertical polarization.

Finally decided on a flush disc antenna. This design came from the John
Kraus antenna handbook, so I will need to build in myself as there is none
available. But it will mount on the inside surface of the belly of my
motorglider. Just in the process of fabricating one.

I also purchased a Becker and it should do nicely.
