Radials - Vertical Antennas - Ground Resistance
Rudy Severns N6LF has conducted an extensive study of radials and other interesting aspects of antennas. He published a series of articles on these subjects in ARRL’s QEX magazine. He also maintains a website (linked below) where he publishes his articles. If you have questions about radials, Rudy probably has your answer.
