FIELD: communication.
SUBSTANCE: invention refers to communication engineering. Technical result is achieved due to that a communication system of the super low frequency and the extremely low frequency ranges with deeply submerged and remote objects comprises a transmitting system consisting of a master oscillator, a modulator, a system of control, protection and automation, a power amplifier, a matching device, an antenna current indicator and a current source, herewith reception and registration of the radiation created by SLF-ELF-generators are carried out by means of a towed cable antenna, an antenna amplifier and a receiver of the SLF-ELF range arranged onboard an underwater object, characterized by that it additionally includes N converters, N grounders of an antenna system made in the form of an elongated straight line consisting of N parts, sections, of an underground unshielded cable, an antenna system with length 
equal to several dozens of hundreds of kilometers, each of the N converters is made identical and comprises: a section of the underground cable with a length of not more than 20 km in the antenna system, a source of electric power supply of each unit via the converter power supply circuits, an information transformer, a power transformer, the first amplifier, an integrated circuit (chain), second valve B.2, a differential circuit, first valve B.1, the second amplifier, the third amplifier, a clock pulse generator, a modulator, a power amplifier, a current transformer, a power controller at the input of the power amplifier, 
– current in the N-1 section of the antenna system with the length of up to 20 km; 
$ – current in the N section of the antenna system with the length of up to 20 km; 
– current difference of the N-1 section of the antenna and the N section of the antenna; each of the N current transformers contains a three-winding transformer to provide specified parameters of current in all sections of the antenna system.
EFFECT: technical result is providing electromagnetic compatibility with radioelectronic devices, power transmission lines, cable communication lines, engineering structures and ensuring environmental safety within the area of the radio station antenna system deployment.
