FIELD: radio engineering.
SUBSTANCE: system includes command transmitter, "n" identical modules each of which includes voltage generator connected through matching device to an individual low-lying horizontally oriented transmitting antenna with earth leads on ends, module control unit, inverter adjustment and protection unit, adjustable rectifier, receiving antenna with antenna amplifier and receiver of SLF-ELF range. Each generator consists of several independent in-series connected inverters connected to adjustable rectifier. Transmitting antenna of each module is made in the form of a power transmission line with lightning protection cable connected on the ends to earth leads of the antenna and cut throughout its length into several sections isolated from antenna supports. Earth leads of each transmitting antenna are made in the form of parallel located metal wires connected to each other and directed to opposite sides from the antenna centre.
EFFECT: improving the range and depth of communication.
