Here to There: Radio Wave Propagation – Tools You Can Use for the Current Solar Cycle by ARRL Inc.

Propagation Know-How Amateur radio communication depends upon the movement of radio waves, and hams spend a lot of time designing a station that will send those waves in a desired direction. As soon as your transmission leaves your antenna, however, it is subject to the often-misunderstood effects of propagation.. Here to There: Radio Wave Propagation presents the principles of signal propagation in an easy-to-understand style. It provides practical advice on understanding what’s going on in the ionosphere and troposphere, how takeoff angle impacts your transmission, how far you can really communicate over VHF and UHF, and much more. Knowing ionospheric structures, how they form, and which bands they interact with will prepare you for practical operating and help you make the most of your time on the air. Fundamentals of Radio Wave Propagation A breakdown of the science underpinning your communications. The Sun and Solar Activity Read more
