Default Cecil, was it you that mention a "windom balun?"

The one I remember was about the Carolina Windom 4:1 voltage balun at
the feedpoint and the 1:1 choke-isolator 20' down the coax. The
original Windom was fed, Marconi style, against ground.

I have a "weird thing" about windoms ... I just don't trust an antenna
which "manipulates" RF on the feedline in "beneficial" ways and has a
religious cult following ... insane quirk of mine, really. lol Now I
don't have the room ... moved again.

If the wife had her way, we would move to Montana next to a favorite
sister and brother ... there we would have the room! lol

Just throwing in my comments on the so called Carolina Windom like Cecil
described.
I have one up like that and also an 80 meter dipole and triband beam up to
compare signals with.
Not all cases, but many times the Windom is as good or better than the other
antennas. The beam does beat the Windom by about double the microvolt
signals on the very long signal path.

The balun I am using is suppose to be able to handle the power I am running,
but around 1 kw to the antenna the 4:1 balun overheats after about 5 minuets
and the swr starts going up. There is some current coming down the feedline
as the choke balun 20 feet down the coax is getting warm. It does not do
that with about 1200 watts going into it while connected to a dummy load.


Like most any simple antenna, you throw RF at it and hope the signal goes in
a direction that lets you make contacts. The antenna can be set so that it
is most favorable in one or two directions, but when making contacts all
around, it is difficult to change the direction of the dipole.
