PURPOSE:To obtain an interruption leak coaxial cable device featuring the simple installation, removal and transportation by connecting the terminating equipment possessing the connector at one end and the antenna function at the other end to the leak coaxial cable and then taking up the cable to the shifting bobbin. CONSTITUTION:Connector 2 to be connected to the transmitter/receiver is connected to one end of leak coaxial cable 1, and terminating equipment 3 featuring the antenna function is connected to the other end of cable 1 respectively. Thus cable main body 4 is obtained. Main body 4 is taken up to shifting bobbin 7 comprising rest 5 and bobbin 6 to be installed at the necessary sections only when used. As for equipment 3, external conductor 22 of cable 1 is folded by lambda/4 (lambda: using wavelength) at the terminal, and internal conductor 20 is projected from fold terminal 24 by lambda/4 in order to increase the communication range of the signals. Thus, an interruption leak coaxial cable device featuring the simple installation, removal and transportation can be obtained to be applied suitably for the temporary insurance of communication at the area such as the undergroung market or the like where the wave attenuation is large. |
