摘要

Problem to be solved: to solve the effect of wind from a train or the like, and to provide a leaky coaxial cable laying structure capable of suppressing the effect of contamination, etc., a polyolefin resin material excellent in fire resistance and electrical communication characteristic, and its use for trough structure A communication method and a communication system using the same laying structure are provided.Trough 3 is made of resin.A cable support member 11 is disposed in the closed space formed by the trough 3, and a coaxial cable 5 is mounted on the support portion 33 toward the lower side of the support wire 29.In the present invention, it is possible to realize a construction of a leaky coaxial cable having high rigidity and good linearity.The present invention also provides a communication system using a polyolefin resin material excellent in flame retardancy and communication characteristics, a method of using a trough structure material, a communication method, and a laying structure of a leaky coaxial cable.The communication method and communication system of the present invention can be used to realize a good communication state with the vehicle antenna.Selection diagram
