Practical Antenna Theory
This series of articles deal with the more technical aspects of antennas and the theory behind their use. You will find this guide to be a pragmatic approach to antenna theory. The views expressed here are the author's and are not meant to be the definitive text on the subject. You should also be armed with the knowlege that there may be changes from time to time where technology advances and the author deems it approprate to update the text.
You should do your won research and fill in where there are "learning gaps".
Much of the material in this series is derived from publications by the ARRL. Namely,
© The ARRL Handbook
© The ARRL Antenna Book.
You should consider these publications reference material in this cursory study of a very complex subject. The most recent editions are available from the ARRL Store online and can be seen at many hamfests, but may vary in quality from used to mint conditon, over many past versions. Any should be considered a valuable addition to your reference library on antennas.
I hope you enjoy this. Please email me if you have questions or would like to see a particular subject enhanced.
