April 19: Ed Fong, WB6IQN, on Tri-Band Antennas
Our guest speaker for the April 19 meeting at 7:30 p.m. will be Dr. Edison Fong, WB6IQN, the founder of Ed’s Antennas and inventor of the DBJ-1 and DBJ-2 antenna that was featured in the February 2003 and March 2007 QST.
The DBJ-1 is a highly effective dual-band VHF/UHF base station antenna, while the DBJ-2 is the portable roll-up version. The DBJ-2 won the QST Plaque of the Month Award. Both antennas are featured in the ARRL VHF Antenna Handbook, and also in the ARRL Antenna Classic Handbook. There are over 35,000 of these antennas in use today.
His most recent antenna is the TBJ-1, a tri-band base antenna (144-148 MHz, 222-225MHz, 440-450 MHz) that was featured in the March 2017 issue of QST.
Ed will give a history on how these antennas were developed and the theory behind how they work and why they perform so well. There is no “black magic” to antennas; he will explain this in a practical, non-mathematical manner.
While running a company that produces affordable, high-performance antennas, Dr. Fong also teaches RF Wireless Communications and other courses at the college level. He teaches graduate classes in RF Design and High Speed Interface Design as an instructor at the University of California Santa Cruz-Silicon Valley, and previously held a similar post at UC Berkeley.
Ed was first licensed in 1968 as WN6IQN. He later upgraded to Extra Class (with full 20 WPM CW) with his present call of WB6IQN. He obtained BSEE and MSEE degrees from the University of California at Berkeley, and his Ph.D. from the University of San Francisco.
A Life Senior Member of the IEEE, he has 12 patents and over 40 published papers and books in the area of communications and integrated circuit design. During his 30 year career he has performed worked for Motorola, National Semiconductor, Phillips Semiconductor and Advanced Micro Devices.
