The present draft of these notes, while far from perfect, may be helpful to many amateurs. For that reason I've posted them in their present form with the understanding they will be revised, probably several times, in the coming years.
By all means let me know if I've forgotten something useful and, even more importantly, if I've made a mistake! A lot of other peoples work has been included but the mistakes are all mine!

Antennas
Antennas are a rich field for investigation and innovation, even after more than a hundred years. Since I was first licensed over 65 years ago antennas have been my passion and over the years I've published articles on antennas and notes. 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 time and effort invested in my antennas than in station equipment. This web site provides access to my articles and notes. 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.
