Antenna Seminar

Friday- October 20, 2023

9:00am - 5:00pm

Bishop Ranch Ballroom
Salon E-H 

We have put together an outstanding lineup of speakers who will provide informative and state-of-the-art presentations never heard before on the science of antennas. The Antenna Seminar is a full-day event. Topics range from the basics to more complex antenna concepts.

This seminar usually sells out each year, even standing-room-only attendance. So get your ticket early, if you don't want to miss this outstanding amateur radio event.


Antenna Seminar tickets must be purchased in advance and remain the same as last year's price. There is a $20 additional charge for this Friday all-day Forum.  Additionally, you will be able to ask the experts questions during the “Panel of Experts” session at the end of the day.

A link to the presentation handouts will be distributed to attendees after the convention. The website will have all presentations that were available at the publications deadline.  You will be able to download the documents in PDF format.  Instructions with the download site link will be provided by email after the Antenna Seminar.  

The download site will be available for one month following the convention.

A Pacificon℠ General Admission ticket (aka "Convention Badge") is also required to attend.

Buy tickets for Pacificon℠ and the Antenna Seminar. Space is limited.

Title: Grow An Antenna ... from Seeds

Amateur antennas are universally made of metal conductors, often made by "bending metal." Trees, shrubs, buildings and other objects near an antenna, are regarded as nuisances that reduce an antenna's performance by distorting its pattern or adding unknown losses. Antenna modeling software is viewed as incapable of modeling such effects. In this presentation K6OIK will reveal how popular thin-wire antenna modeling programs EZNEC, 4nec2, MiniNEC, and MMANA-GAL can be used to model dielectric objects. A surprise is that trees can do more than just support an antenna. They can be an effective part of an antenna. In a detailed study, K6OIK will show how to landscape an antenna farm for improved performance - what seeds to plant and where to plant them!
