Abstract

PURPOSE:To elongate the distance range of a mobile radio equipment by providing repeaters that have a transmission-reception part and control part between two leakage coaxial cables and then by sending a transmission frequency through one propagation line and a reception frequency through the other propagation line. CONSTITUTION:Mobile radio equipment 10 of transmission-reception frequency f1 and mobile radio equipment 11 of transmission-reception frequency f2 are confronted each other and two leakage cables 9 are used as propagation paths. Between those two propagation paths, repeaters 12 and 13 are provided. Then, the frequency of the receiver of repeater 13 is set to f1, and that of the transmitter to f2; and the frequency of the receiver of repeater 13 is set to f2, and that of the transmitter to f2. Further, repeaters 12 and 13 are provided with control parts 14 respectively and only when receivers R11 and R22 are in operation, transmitters T21 and T12 are put into operation. Thus, one propagation path is dedicated to the transmission frequency, and the other to the reception frequency.
