RADIO ANTENNAS—CREATION AND BEHAVIOR OF RADIO WAVES

"Presents an over-view of the generation and the behavior of radio waves. Animated diagrams, combined with real photography, discuss static fields, magnetic lines of force, high-frequency generators, the behavior of radio waves in space, and the reflection of radio waves." "There follows a discussion of what is known as skip distance ground waves and the fading and the distortions that result from a conflict between waves." "With considerable supplementation will be useful in the discussion of radio waves as applied to the navigation of aircraft." Central Washington college of educ.
