Ordering Information - We DO NOT take orders in the Store App here. Please email or call and after it is clear what you want, we send you an invoice. The App Store caused too much confusion. We ship USPS Ground Advantage and you pay the actual shipping amount. At this time we offer 7 antenna models. The following are the models we presently offer and their prices. Prices do not include the 3/4 inch 200 psi pvc pipe. The pvc pipe is Lowe's item number 23990. We accept payments via personal check or Paypal.
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). Antenna Design Course (EECS 416) and I/O Design Fundamentals (EECS 440). Previously I was with UC Berkeley, ext teaching RF Wireless Design.
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 Zoom.
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 40,000 of these antennas in the last 20 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.
