Antennas From The Ground Up

L. B. Cebik, W4RNL

The following series of articles was originally prepared for publication in Low Down, the journal of the Colorado QRP Club. The series is designed to present fundamental antenna information, concentrating most fully on lower HF band wire antennas and related topics, to QRP operators. Since Low Down has devolved into a small newsletter, I have terminated the series and will place the remaining pre-prepared items here.

Note: This series (with revisions and enhancements) are available in book form under the titles from MFJ:
