PURPOSE:To make it possible to secure radio services nearly over the region in a cable laid section even if one part of a cable is broken, by feeding a current from not only the feeder end of a coaxial leakage cable but also its terminal end. CONSTITUTION:To the terminal end of coaxial leakage cable LCX2, terminal box 8 is connected through feeder 7. In terminal box 8, therefore, terminator 5 is connected, being detachable, to feeder 7 via coupler 9 and if one part of LCX 2 is broken due to a fire, terminator 5 in terminal box 8 is removed and movable radio unit 6a, for example, is connected to connector 9, thereby making it possible to secure the radio service that another movable radio unit 6b, etc., receives indication from radio unit 6a between the terminal end and the wire-broken part. Further, since the ratio service is being done between the feeder end and the wire broken part by transmitter-receiver 2, the radio service can be secured nearly over the entire region even if one part of LCX 2 is broken. |
