The New England Sci-Tech Amateur Radio Society will meet on-line and in-person on April 25, 2023 at 7 PM and feature: “Dual Band Antennas” by Ed Fong, WB6IQN.
Description: Ed Fong, WB6IQN, is the inventor of the DBJ-1 and DBJ-2 antennas that were featured in the February 2003 and March 2007 QST. His most recent antenna is the TBJ-1, a tri-band base antenna that was published in the March 2017 QST. The DBJ-1 is a highly effective dual band VHF/UHF base station antenna and the DBJ-2 is the portable roll up version. The DBJ-2 won the QST Plaque of the Month Award. Both of these antennas are featured in the ARRL VHF antenna Handbook and also in the ARRL Antenna Classic Handbook. There are over 40,000 of these antennas in use today. About half are used by hams and the other half by government and commercial agencies. Ed will give a history on how these antennas were developed and the theory on how and why they work so well.
