===========
Well, it's really the same thing as a halo, which in turn is the same thing
as a dipole that's been bent into a circle (or in this case a square) and
trimmed so that it's resonant after taking account of the proximity effect
at the ends. It emits horizontally polarized radiation in all directions,
and generally works fine. Several can be combined for an all-bander (see
http://www.g3tpw.co.uk/). If fed with coax, it will benefit from a coaxial
choke mounted near the antenna.
