PROBLEM TO BE SOLVED: To allow receiving and originating radio wave to be selected and to automatically flow to a receiving circuit or to flow from an originating circuit by the same antenna by fixing a transmission/reception switch at the contact point of an external receiving and originating antenna and a receiving and originating circuit. SOLUTION: A radio wave call-originated by a base station is received by an external antenna, passes through a connector extended from a repeater 1 through an antenna wire, and flows to a receiving circuit by the transmission/ reception switch 14. Then the flow of the radio wave amplified by an amplifier 11 is connected to the antenna of a portable telephone equipment with a clipper by the connectors 2 and 10 of the portable telephone equipment, flows to the receiving circuit of the portable telephone equipment, and then flows to the amplifier of a call originating circuit 12 by the switch 14, and the radio wave set to be prescribed output flows to the switch 14 connected to the external antenna, passes through the connectors 2 and 10 and flows to the external antenna to be originated. |
