Antenna matching device tuning for type ZhRU radiostations
Abstract
The antennas employed with the ZhR series radiostations are lengths of wire 11 to 14 meters long suspended 0.4 to 0.6 meters above the locomotive cab, with their end grounded through the locomotive cab. The antenna matching device must be tuned properly, because it is this device which finally determines the effective transmitter power and the condition of the antenna feed devices. Adjustment of the antenna matching device by means of front-panel controls is described, and the meanings of various ammeter readings are interpreted.
