How about Chico, Harpo, and Groucho?

Art Unwin hopes to stump us by not defining what he means if anything by
"equilibrium". A synonym, "balance" is often used in radio. Terman
defines "balance" on page 901 of his 1955 opus:
"It is sometimes desirable to deliver power to a grounded antenna
through a two-wire transmission line or, conversely, to use a coaxial
cable line to deliver power to an ungrounded antenna system that is
symmetrical with respect to ground. In either case, it is necessary to
convert between a balanced system that is symmetrical with respect to
ground, and an unbalanced system in which one side is grounded."

That seems to capture a problem we had here. Art is unbalanced and we
are well grounded. None of us is in equilibrium.

Ah! There we have chaotic harmony, not equilibrium. Perhaps more
"attuned" to Gussian arrays. For haberdashery (what I presume Art
describes here in this group), Hart, Shaffner & Marx is the zenith of
equilibrium in dress (but not antennas).

More the problem is that Art may have redefined the word "shoebox"
which must be his metric standard for something the size of a WalMart
store. If he had an antenna the size of two WalMart stores
side-by-side, then yes, his claims would make sense.

So, in the vocabulary of Authur-speak:
Shoebox: One WalMart building.
Equilibrium: Matching fashions for men's levitation wear.
Paramagnetic: Skydiving at the North Pole.
Diamagnetic: Calorie cutting by eating only magenta colored food.
Array: Any jumble of rusted barbed wire sections.
Director: A reflector of an array.
Reflector: A director of an array.
Radiation: Bugs that hit your windshield (aka particels)
Resonance: Wiper action of flicking radiation off your windshield.
Antenna: A patent for a method of dividing by zero in checkbooks.
