What did you have in mind? Do you want to profit from the idea, or
just make it freely available? Just what help (if any) are you looking
for: help with analysis, help with writing a description, help with
promoting it, help reviewing the idea and comparing and contrasting it
to previous ideas, or what? There are lots of folk here who could
potentially have an interest, and some even have a deep enough
understanding of antennas that they might actually be able to help.

Cheers,
Tom
