Default Yagi efficiency

As my girlfriend likes to say "WORDS MEAN THINGS!"

Having a weird definition of efficiency doesn't help anyone out.

Needing an antenna with super-high-gain at one particular elevation and
azimuth angle is a weird, but... sort of valid question... but has
nothing to do with the efficiency of said antenna.

Hi Dan,

From discussions of years past with the chipster, his novel k2 fractal
flyer antenna (heavily constrained with unique parameters) offered the
"best" gain at 10 degrees that couldn't be bettered by anyone. He
took umbrage when this claim was examined in the modeler ("you can't
make a copy of that antenna! I own the rights!"):
http://www.qsl.net/kb7qhc/antenna/fr...r/k2/index.htm

It turned out that the word "Best" meant -4.63 dBi - which I promptly
bettered by more than half a dB (in an unpublished design I call the
Foolish fractal Flyer). The chipster also made efficiency claims
similar to Art's (that is, using the same corruption of language). It
didn't take long to flush that efficiency with the same merits.

The moral of inventing meanings for words is that those meanings have
a short shelf life. This kind of thing doesn't even last out a week
in the white house press room.
