We are ACCEPTING ORDERS - and have built up an inventory. Just email me and tell me what you need.
Latest status - read below.
Obtaining RAW materials for our antennas has become a major hurdle. HRO's (Ham Radio Outlet- via Seminal Wiring and Cable) supplier of our
custom twinlead is low on copper. Apparently raw copper comes from South America. The price quotes now for twinlead is $0.46 per foot. This is 2x the price from a few months ago.
Our connectors and adapters must now be shipped DHL EXPRESS when coming from Asian - otherwise the materials never arrive.
They sit in a shipping container on board ship in Long Beach CA. With DHL EXPRESS we are paying over $200 for each shipment.
We have had to raise prices slightly due to increase cost in raw materials and also our ability to meet high demand. Postage
also has increased.
The price of pvc pipe has now doubled from a few years ago. Lowe's 200 psi pvc for 10ft section is now $3.84 on the West Coast.
I use to purchase this same pipe for $1.60. The #14 copper wire we purchase for the GMRS 5dB gain antenna use to sell for
$34 for 500ft. It is now $70.
Again thanks for supporting our group. Contact Kai Chen or Jason Johnston - they also may have stock.
East Coast distributor - KBCubed - if you order from them, you may save some postage if you are in the East Coast.
www.kbcubed.com. Their phone number is 201-660-5051.
Our Mid West distributor is - Grapevine Radio - https://grapevineamateurradio.com - Jason Johnston is the owner.
We now can ship to Canada direct. Please email me if you wish to order from Canada.
Antennas are used as our only a fundraiser for my RF Wireless group at UC Santa Cruz - Silicon Valley. My primary job is teaching at the University.

Thanks for your understanding.

Welcome to our Website. My name is Ed Fong WB6IQN and I am currently on the faculty of UC Santa Cruz- Silicon Valley.

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.
