Tom,

How would that work in a folded dipole? Surely it's not the
differential mode "stub" you're trying to shorten - it's the common-
mode radiator.

Hi Steve,
I have no idea what Cecil will find if he tries his
theory on this. However, according to Cecil's favorite text, a
folded dipole's behavior can be analyzed by assuming that its
current "is decomposed into two distinct modes: a transmission
line mode and an antenna mode." (From Balanis, _Antenna Theory_)
You've got EZNEC; you can try this, too. It won't cost you anything,
and, if nothing else, you might get the satisfaction of telling me
how wrong I am.
