The design of antennas is a rich field for investigation and innovation. Even after more than a hundred years of work in the field we can still gain new insights and ideas. Since I was first licensed over 60 years ago antennas have been my passion and over the years I've published articles on antennas and continue to study and write about them.
Amateurs rarely design and build their own equipment these days but antennas are very often home brewed and provide a means for improving station performance at modest cost. 60 years ago Tom Erdmann, W7DND(SK), told me that if I had $100, I should spend the first $90 on the antenna, the next $9 for the receiver and the final $1 on the transmitter. Of course prices have gone up bit but those proportions are still sound advice. I can honestly say I have a lot more money invested in my antennas than in my station equipment.
This web site provides access to my articles and a place to post new work from time to time. Except for articles published elsewhere, much of what I'll be posting will be informal and subject to change as I learn more. The work reported here is a mix of analytic (calculations), NEC modeling and field experiments on actual antennas. Each of these has it's place but the best picture emerges when all three techniques are combined.Please note, I try to close each post to comments. Once in a while I forget to push the right button and a post may be open. However, I assume I'm perfect and always have the posts closed, so I don't look for comments.
