Robert (Bob) Zavrel, W7SX, a world recognized antenna expert, will be our guest speaker on March 11th on Google Meets. Bob is Author of Antenna Physics: An Introduction (ARRL, 2nd edition). He has over 100 technical publications. His 1987 article in Ham Radio Magazine was the first block diagram of an SDR receiver. Licensed since 1965, Bob has numerous DXCC awards, all accomplished with tree supported wire antennas. Bob earned a B.S. in Physics from the University of Oregon, is an IEEE life and senior member, an ARRL life member and volunteer technical advisor for over 40 years. He has lectured on RF engineering at Stanford, Berkley, Univ. of Alabama, several European organizations, and was adjunct professor of Electrical Engineering at Gonzaga University in Spokane. ARRL awarded Bob the 2025 Doug DeMaw, W1FB Technical Excellence for his May/June 2025 QEX article “Calculating Antenna Radiation Resistance with Emphasis on Ground-Mounted Verticals.” Bob’s seminar presentation to CARC will include such topics as antenna aperture, radiation resistance and mechanics, basics of RF power related to antennas, and small loop antennas.
