Default Minimizing Common Mode Currents by Simple Grounding?

Well . . this is a semantics & definitions issue as an ME I'll leave
for you EEs to sort out. I'm just another hobbyist who calls any
conductive structure with it's first resonance at a half wavelemgth of
some specific frequency a "dipole" independent of where it's fed and
how it's oriented. Which of course lays me open to the prospect of
getting gored good by purists and others who have copies of the IEEE
dictionary.


Actually Brian, the IEEE Dictionary seems to agree with you.
It doesn't say a thing about the feedpoint position of dipoles.
Is an OCF a dipole? Is it a dipole if one of the poles is only
one inch long? The IEEE Dictionary seems to say that anything
that walks like a dipole, talks like a dipole, and radiates
like a dipole *is* a dipole, by definition. :-)


Heh. Somewhere along the line a long time ago some sage somewhere
stated that there are only two basic types of antennas, point radiators
which are really difficult to build and dipoles and their variants. The
concept stuck and I've been wearing it ever since.
