FIELD: oil, gas and coke-chemical industry.
SUBSTANCE: invention can be used for data transmission over a network of gas pipelines using a transmission medium connected to a system of pipelines. Essence of the invention consists in the fact that in-pipe space is used as the transfer medium, in which data are transmitted by means of propagating electromagnetic waves H01, excited by means of antenna elements located inside broadenings filled with a high-frequency dielectric, wherein the antenna elements are arranged radially symmetrically, creating a longitudinal electric field corresponding to the field of the H01 wave, and are connected to the conducting line.
EFFECT: high reliability of the communication system.
