Default End-feeding dipoles

It should not hurt. My dictionary says a dipole antenna is a straight
conductor usually fed in the center.

However, dipole characteristics are determined by current distribution,
not the feeding if the feeder doesn`t radiate.


Seems to me, technically speaking, the two poles in
a "dipole" are electrical with opposite voltage polarities
at each end of the 1/2WL dipole. An electric monopole
has only one electrical pole, like a magnetic monopole
has only one magnetic pole.

A 1/2WL end-fed wire would then technically be a dipole
and the passive elements on a resonant Yagi would be
dipoles.
