adio propagation via the ionosphere is a fascinating and important means of long-distance radio communication. Thousands of hams and commercial operators use the ionosphere every day to make contacts over vast dis- tances. To effectively use these propagation modes to their fullest, however, we must understand the is the ions that give their name to the ionosphere, but it is the much lighter and more freely moving electrons which are important in terms of HF (high frequency) radio propagation. The free electrons in the ionosphere cause HF radio waves to be refracted. (bent) and eventually reflected back to earth. The greater the density 22 Nov 2017 Supporting Files: A solutions manual is available for this title.

For frequencies beyond 40 MHz, the wave tend to penetrate through the atmosphere versus being reflected. The major usefulness of the ionosphere is that the reflections enable wave propagation over a much larger distance than would be possible with line-of-sight or even atmospheric refraction effects.
