Off-Center Feed - The Windom Antenna - The Windom antenna was widely used in the 1930s and is named after the amateur that wrote a comprehensive article about it

Windom Antenna with 4:1 balun - The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers .
