Radio Wave Propagation Studies

The combined effects of apparent wave direction shifts and fading, of signals from a crossed coil type of radio beacon as received on airplanes in flight at night, are described. A brief explanation of the operation of such a beacon is given. The results of observations of similar signals at night received on an automobile, together with some general conclusions, are mentioned.
