One of the things I enjoy about antennas is the opportunity to build some of the classic antenna designs used in the early days of Amateur Radio. 

The Windom Antenna is a good example of an early antenna design which continues in a variety of variants today.

The modern Windom Antenna is a close cousin of the original off-center-fed dipole created by Loren Windom (ex-W8GZ) back in the early 1920s.  Windom's original idea was to design an off-center-fed (OCF) horizontal antenna to present a feed point impedance of around 600 ohms, close enough to match the surge impedance of a single-wire feed line.  Nowadays, variants of the Windom Antenna are fed by coaxial cable and a variety of balanced feed lines.

In this video from Stan Gibilisco (W1GV) we get a thorough understanding of the theory, design, construction, and use of a "modern-day" Windom Antenna using a variety of feed line configurations.
