PURPOSE:To ensure the highly efficient radio communication by forming the radio coupler insertion use concave groove at part of the sheath and the insulator near the electromagnetic wave leak notch part of the external conductor located along the length direction of the leak coaxial cable and then securing the close coupling state for the radio coupler with the internal electromagnetic field. CONSTITUTION:Radio coupler insertin use concavity 7 into which radio coupler 8 is inserted is formed at part of protective sheath 6 of the most outer layer as well as at insulator 2 near electromagnetic wave leak notch part 5 provided to external conductor 4 located along the length direction of central conductor 1 of the leak coaxial cable. Then concavity 7 is covered with metal shielding plate 9 which can be attached/detached and breached freely, and a close coupling is given to coupler 8 with the internal electromanetic field to reduce the mutual disturbance with other communication system. Thus, the highly efficient radio communication is ensured. |
