[aprssig] TransAtlantic Balloon on 28 MHz ?

Do you have a 10 meter (28 MHz) vertically polarized beam?

We are working on a 28 MHz transatlantic Balloon with a CW transmitter on 10m using (of course) a vertical dipole.

It will have no GPS, so tracking will be entirely by beam headings and some signal-strength assessment.

Just wondering if anyone has a vertical beam.

A horizontal beam will be useless for direction finding.  All it will do is point to whatever is reflecting the energy into the strongest horizontal component...
