Bob and all,
During an emergency landing too many aircraft go over on their backs. I suspect that the back contact and sliding in too many instances scrapes off or otherwise damages antenna like the ELT typically use.

From that situation, I have wondered about a design concept that would allow the ELT to feed either two or one antennas with enough radiation to get someone's attention. The thought goes something like this. Have an antenna both top and bottom of the fuselage region. Hoping that one survives the impact and will radiate the ELT signal.

Any thoughts about a design that could "reasonably" match and feed either two (if both survive) or the remaining antenna....
