• Broadband Transmitting Wire Antennas for 160 through 10 Meters 
  QST November 1995, pp.22-24
  A traveling-wave antenna offers some attractive qualities for your station: 50 ohm feedpoint at ground level, no tuner required, horizontal and vertical radiation components, no radials, nothing in the air but wire, and flexible size and height requirements.
• Zip-Cord Antennas - Do They Work?
  QST March 1979, pp. 31-32
