The original Windom *was* an intentionally off center fed multi-band
antenna. Anybody have info on the Windom from the 40's 40's. Dad used
one, but I don't know what he did.

Thanks.

I think it's one of those deals that goes: yes, there is an imbalance
situation created. But, it's not significant in the big picture.

I can live with that!

YEP!!

134 feet long.

Fed 46 feet from one end with a SINGLE WIRE [NO COAX, NO TWIN LEAD, NO
BALUN, etc.]. Very good tuning system required. Allegedly something
close to 600 ohms at feedpoint. More wishful thinking than reality. [In
those days people were not obsessed with VSWR = 1.000001 to 1. ]

Some feed lengths produced a 'hot' key or mike. Changed length of
feedline to get rf out of shack. X

80, 40, 20, 10 meters.

All current model 'Windoms' are true fakes !!!

Wasn't the design criteria something like "make it 40 feet high and feed
it 40 feet off-center"?

The Windom was named for the amateur who described it in an article. It
was a 1/2-wavelengrh at its lowest frequency of use. A single feed wire
is connected at 0.34 X the length of the antenna, from one end.

The Windom works best over highly conductive earth using a versatile
matching network to the transmitter.

The 1/3 length feedpoint from one end is about 1/6 the distance from the
antenna`s centerpoint. 40 feet off center, makes the antenna 240 feet
long. This is 1/2-WL at 146 meters. It is 12 meters high. This is 1/4-WL
at 48 meters and
1/2-WL at 24 meters.

Although Loren Windom, W8ZG/W8GZ, wrote an article about the antenna for QST, he
had nothing to do with its development, even though it has taken on his name.
Loren was a student at Ohio State while Professors Everitt and Byrne were
physics professors and Loren was one of their students. He trailed along with
them during their experiments with the off-center fed dipole, wrote up the
specifics, submitted his writing to QST, after which the hams started using that
antenna. Because Windom's name was on the article as the author, the antenna
became known as the Windom in ham circles.
