Hi Chris,

Half-Isotropic (if you allow for total field - you didn't specify and
any protoplasm could game that loose specification) at:
http://www.qsl.net/kb7qhc/antenna/In...-1%20Field.gif

The design has been kicking around for 10+ years now at that link, and
not even original when I posted it.

As for gaming the lack of polarization spec, I might simply offer that
it doesn't matter - if you use an isotropic detecting antenna to
measure the field of this antenna model in the link. For that
isotropic detecting antenna, I would offer a golf-ball lump of coal
and a thermistor.
