Default Minimizing Common Mode Currents by Simple Grounding?

Heh. Somewhere along the line a long time ago some sage somewhere

There's got to be a history of the word dipole still in
existence. If you look at the Wikipedia definition of
"dipole", it refers to the equal and opposite charges
existing at two points, akin to the equal and opposite
charges existing at a point in time at the two ends of
a 1/2WL piece of wire. Your 1/2WL continuous piece of
conductor has two electromagnetic poles somewhat akin
to the earth having two magnetic poles. I suspect it was
ignorant hams who changed the meaning to two conductive
fishin' poles pointed in opposite directions and fed in
the middle. :-)
