When it comes to understanding how antennas really work, then the "go to" ham is Bob Zavrel, W7SX, author of the ARRL book, Antenna Physics - An Introduction. Through this book, Bob bridges the gap between "how to" antenna books, and calculus based antenna theory books for engineers. Bob has a long resume in radio and electronics, is the accidental creator of the Signetic NE602 mixer chip. Bob was my guest in this interview over 200 episodes ago and shares his story in this replay in this QSO Today.
