FIELD: radio engineering.
SUBSTANCE: system has communication channel, made in form of metallic pipe, transmitter and isolated transmitting antenna, mounted on moving object, which is placed inside the pipe, two receivers, positioned outside the pipe at its ends, while each receiver is provided with antenna, which is positioned above the pipe on outer side, while each antenna has flat dielectric frame in form of radially positioned leafs with spaces and winding, made by isolated wire in form of spiral, while wire of each coil of spiral circles one or other side of each leaf, dielectric frame is bent in one plane in form of semi-circle.
EFFECT: higher precision, broader functional capabilities.
