Nice FLARM antenna mount in ASG-29

Ramy,

That's exactly what I've thought. I would have put my Flarm antenna in the nose of my glider like you did except that space was already occupied by a transponder antenna. So, last fall I embarked on designing and modelling a dipole like antenna that is constructed of thin spring wire (visually unobstructive). It has a 4 element wire counterpoise that lives below the glare shield with a single vertical element above the glare shield. I'm using a small breakaway coaxial antenna which also comprises the mounting through the glareshield. I'm planning to attend the Perry contest so I should get data on how well it performs there.

I had in mind that I might manufacture this antenna as a commercial endeavor. However, when I disclosed the design to Flarm they had certain objections. The objection that I couldn't dismiss was that the Flarm radio circuit can be damaged by static discharge and the thin exposed element would increase that suseptibility.
