Antenna Techniques for Achieving Multi-Band Operation at VHF and UHF
Edison Fong, WB6IQN

Our speaker is the inventor of the DBJ-1 and DBJ-2 antenna that was featured in the February 2003 and March 2007 QST.    His most recent antenna was the TBJ-1 – a tri-band base antenna that was published in 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 20,000 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.  There is no “black magic” to antennas.  He will explain in a non-mathematical manner to convince you for overall performance and simplicity his approach is one of the most practical.
