The Constants of Aircraft Trailing Antennas

This paper constitutes a report on the results of the measurement of the trailing antenna constants on several types of aircraft including the dirigible Los Angeles. A brief description of the apparatus and method is given. Curves for a typical airplane and dirigible are presented and from these curves conclusions are drawn as to the center of radiation and the relation between antenna resistance and the center of radiation. The uniformilty of antenna constants of heavier-than-air craft is noted, also the negligible effect of structural differences, speed, and weight on antenna characteristics.
