The question is, what is good enough?  To minimize radiation from an open
wire tuned feeder requires, I believe, that the currents in the two wires to
be equal in magnitude and have a phase difference of 180 degrees at the
feedpoint of the feedline.  Feeding a slanted dipole, which is certainly an
unbalanced antenna, is it practical to build a 1:1 balun on a ferrite core
(core type choice?) that, when placed on the output of an unbalanced tuner,
is good enough to force the desired currents from 40m thru 10m without
excesive losses?   Using an LC inductively coupled balanced tuner on such an
unbalanced antenna will not produce the desired results--deliberately
unbalancing the LC tuner by offsetting the taps on the coil will sometimes
get close for me.
