Notwithstanding all the focus on current baluns, a current balun does not
(by itself) prevent common mode current on an OCF Dipole feedline. The
feedline has assymetric mutual coupling to the dipole and can not be
expected in any configuration of significant length to be balanced wrt the
dipole over a wide frequency range.
