THE NON ELECTRICAL MACHINERY AND APPLIANCES COMMUNICATION SYSTEM WHICH UTILIZES 1 CYCLE 2 LINE ANTENNA SYSTEM

摘要

A radio transceiver communication system using a 1 cycle 2 line antenna mode is provided to improve stability of the system by performing transmission and reception after respectively separating transmitters and receivers of a main repeater and a line repeater antenna. A main repeater(100) where a transmitter and a receiver are installed in one case(500) in order to receive a radio transceiver signal is configured in the ground. Transmitting and receiving line repeaters(200) having an antenna(400') so as to transceive the ground radio transceiver signal and underground radio transceiver signal are configured under ground. To separately perform transmission and reception by using one frequency to the ground or the underground, transmitting and receiving cables(300) are respectively connected to main transmitting and receiving units of the main repeater and the transmitting and receiving line repeaters.
