One of my favorite "classic" hf antennas is the off-center-fed dipole known as the "Windom Antenna." The original design was created by Loren Windom (W8GZ) in 1922. This off-center multiband antenna was fed just by a single wire connected on 1/3 of the antenna's overall length. The feed impedance was approximately 600 ohms.
Modern day descendants of Windom's original design use open-wire feeders to attain multiband hf capability, thus reducing some of the TVI and other interference issues commonly found in the single wire feed system.
In this video, Stan Gibilisco (W1GV) explains the general theory behind the "Windom Antenna" and outlines some of general parameters and performance capabilities of this "classic" wire antenna. Properly designed, this antenna gives multiband HF performance at minimum cost.
