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.
