Episode 105 - Robert Zavrel - W7SX
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, and shares his story with us in this QSO Today.
