I just pinched myself; I'm not dreaming and it's not April 1st, so I guess
you're serious.
You are also so wrong on so many points, I'm not going to waste time trying to
refute or correct them.
Jim, please ignore everything said below.

Your feed line will do the job by itself so no additional "balun" is needed.
Keep in mind that a 1:1 balun is really just a length of feed line, usually
wound on a toroidal core to make the required length shorter than if it was
in open air. The "old-school" baluns were just a pair of air wound coils.
If your balanced feed line is at least 1/4 wavelength long, the currents
will be "balanced" (equal and out of phase) at the antenna. That assumes
your antenna is perfectly balanced to provide a perfectly balanced load,
which "balanced" antennas almost never do. There are just too many
variables. So expect excellent results even with shorter feed lines. The
amount of radiation (or pickup) from the feed line even at the rig end is
small in any case.
Connect one side of the open wire feed line to the KAT100 SO-239 center pin
and the other to the KAT100 ground terminal.

K2/100 and KAT100 here.
I am changing around my modest antenna configuration now. I have been using
the K2/100 with my AH-4, and now wish to use the KAT100 with balanced
feedline antennas.
What balun, homebrew or commercial, if any, should I use? I almost always
run 5 watts, all CW.
