It's totally new to me. I just looked at Google images for a few minutes.
Nice looking constructions. The thing that struck me most was your
description of directionality, non-resonance (at lest, not standing wave),
long compared to wavelength, and termination by a resistance. All these
things can be said of a Bevarage too, but they're obviously very different
too. I don't know what the relation is.

A fair antenna is you have a bunch of telephone poles and a huge piece
of empty ground.

Otherwise people these days use log-periodics for better performance
and a lot smaller footprint.
