Abstract

PURPOSE:To increase the communication distance of a wireless interphone by improving reception sensitivity, by supplying a signal from a transmitter to a receiver by the antenna of a TV community device. CONSTITUTION:A signal from an outdoor transmitter 11 is emitted from an antenna 12 and then received by an antenna 2. THis received signal from a line 3 is amplified by a booster 4 an then led from a distributor 5 to branching devices 8 and 9 through lines 6 and 7, and a signal from the branching device 8 is received by a TV receiver 10. Thus, a TV community receiver is onstituted. The transmission freuquency of the transmitter 11 is equal to the reception frequency of a receiver 14, and the frequency is set to a value other than frequencies used for TV broadcasting.
