Welcome to our Website. My name is Ed Fong WB6IQN and I am currently on the faculty of UC Santa Cruz- Silicon Valley. I currently teach the RF Wireless Communications course (EECS 407) and I/O Design Fundamentals (EECS 440). Previously I was with UC Berkeley, ext teaching RF Wireless (EECS 416) from 1998-2011.
If your ham club or communications group wishes me to give a presentation at your meetings, please contact me. There is no charge for my talks. If you are within driving distance I can visit you or I can give a webinar presentation via Skype or Facetime.
I am the inventor of the TBJ-1 (US patent 9,608,336), DBJ-1, DBJ-2 and DBJ-UHF (US patent 8,947,313) antennas which are extremely popular among the ham and commercial communications community. Please email me if you wish copies of these patents. We have sold over 18,000 of these antennas in the last 10 years to hams, commercial and government agencies. I have published numerous articles on these antennas in QST and CQ (QST March 2017. QST February 2003 and QST March 2007, CQ Summer 2012). They also appear in the ARRL VHF/UHF Antenna Classics, ARRL Vol 8 Antenna Compendium, ARRL Vol. 3 Antenna Compendium. The proceeds of these antennas go to support my group at UC Santa Cruz -Santa Clara Valley.
