But, there is the case of loops with the area placed in parallel with the
earth. Those are horizontally polarized. I'm suddenly blank about what
they were called, but fifty years ago it wasn't uncommon to see such
horizontal loops on cars, for 2M and 6M use, since this was before FM so
"base" antennas were generally horizontally polarized.

They were called halos. They were horizontal polarized. If mounted a
fraction of a wavelength over a conducting surface then they became DDRR
antennas (directional discontinuity ring radiator)and vertical
polarized.


Don't forget Squalos (same as halos, but the loop was squared off). I
have no idea why I remember that. Must have been advertised in QST.
