We don't seem to have widely used, descriptive names for these
configurations. Cecil is correct, and perhaps the OCF referred to
should be called an OCF "L". The vertical radiator with a single,
elevated, horizontal, resonant "radial" perhaps should be called an
"L" dipole.
On inspection, either antenna, on a boat with a tuner at the
feedpoint, could be mistaken for the other. You could tell the
difference only by observing how the antenna is operated. If the
antenna is operated only on those frequencies for which the horizontal
element is an odd multiple of a 1/4 wavelength, we would call the
antenna an "L" dipole (or whatever).
If that same antenna were operated not only on those frequencies, but
on all others (HF spectrum) as well, we would call it an OCF "L".
But if, on inspection, the antenna has multiple resonant radials, that
would unambiguously differentiate it from the OCF.
Whenever the two antennas are physically identical, they will
obviously operate identically.
Make sense, Jon? Sorry for the confusion.
Sure. Thanks.
