Ham Radio Signal Behavior: Understanding Propagation, Radiation Angle, and Antenna Performance by John Pertell

Most amateur radio stations fail before the signal ever leaves the antenna. You can have good SWR. You can run more power. You can follow popular antenna designs. And still be weak, inconsistent, or unreadable. If you’re tired of guessing, this book was written for you. If you have ever wondered why an antenna that should work doesn’t, this book explains the exact reasons. Ham Radio Signal Behavior shows what radio waves actually do once they leave the wire—and why small changes in height, geometry, or ground interaction can completely transform performance. This is not an exam-prep manual. This is not a collection of antenna recipes. It is a practical guide to understanding Read more
