Default Carolina Windom without a balun: go figure

I've attached the original article that describes the CW in question.
Three versions of the Carolina Windom are presented: Original single
wire feed, OCF with twinlead and balun, and OCF with 10' length of coax
to a choke balun (1:1). Mine is the middle one. Please see Fig 3A. The
balun is at the bottom of the twin lead (I think I mistakenly referred
to it as ladder line). I added large ferrite beads just below the balun
on the coax as discussed here in the group earlier.


If I'm reading this correctly, you put the balun at the bottom of the twin
lead and the ferrite bead balun just under it.

Many 'Carolina Windoms' use the balun at the feed point, the ladder line or
twin lead under that, and the ferrite bead balun at the bottom of the ladder
line, to which is attached the coax.

Placing the balun (4:1 or whatever) under the twin lead would really do
strange things to the impedance and probably cause the problems you mentioned.
