Hi
Jim Weir designed a copper tape antenna years ago. See sport Aviation

Very simple and cheap.

Hi all,

Thank you everyone who responded.
The project is a small airplane with the fin about 800 mm high (~950 mm
leading edge), so space seems a bit limited for a dipole antenna.
Still looking into any solution.
The idea is to design something mostly DIY for cost reasons, so this
seems to rule out off-the-shelf antennas.
Any ideas ?

BTW, what is the influence of the radiating element width/diameter vs
selectivity or else ?
Any hard facts on the subject ?

Thanks for any input,
