Now, it is assumed that the video output terminal 2 of the video tape recorder 1 is connected to the booster 3, and the video output of an empty channel (for example, the second channel) of the television receiver is sent from the video output terminal 2. . This video output is directly amplified by the booster 3, and the output is input to the linear amplifier 4 via the attenuator 5. This is to prevent the inputs of attenuators 5 & -j and linear amplifier 4 from exceeding appropriate values. The output amplified by the linear amplifier 4 so as to obtain a predetermined power is supplied to the antenna 7 via the Ronogus filter.
The radio waves of the empty channel are transmitted from. In addition, the output is 15% within 100 meters as stipulated by the Radio Law.
It is required that the electric field strength be less than m/v.
