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.
