For many months I've been working on a set of design notes LF-MF antennas intended for hams. These notes still have a very long way to go but there has been sufficient progress that the present draft of the notes may be helpful to many amateurs. For that reason I've decided to post the notes in their present form with the understanding that these notes will be revised, probably several times, over the coming year(s). The portion of the notes I've posted are mostly practical examples with a minimum of math. This will be satisfactory for most users, however, some of you are more sophisticated with technical backgrounds who would like to see the BEEF, i.e. where does all this stuff come from? I'm in the process of creating a series of appendixes which contain all the math and detailed explanations of things like proximity and skin effects, self-resonance in inductors, soil electrical characteristics, etc. These are referenced in the posted text but for the most part all you see at this time is "Appendix TBD". The appendixes will be added over the coming year as I get time to clean them up and upload.
By all means let me know if I've forgotten something useful and even more importantly, if I've made a mistake! There is a lot of other peoples work here but the mistakes are all mine!
