The hallmark of a rhombic is that is long compared to the wavelength of
operation in order to achieve directionality (that is, gain in a

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.
