Abstract

This paper presents a model developed for the output circuit of ULF range radio transmitting unit working on a system of two parallel-connected antennas connected to the switching generator through a matching transformer. The model proposed, in addition to magnetic coupling of two antennas, takes into account galvanic coupling of their grounding electrodes resulting in emergence of a balancing ground current. The band pass of the two-antenna system and additional power losses caused by the balancing current were also determined.
