ABSTRACT:
A wireless receiving subsystem operatively connectable to a broadcast receiver unit having a frequency tuner has an antenna with a feed point, an amplifier located essentially at the feed point, and a transmission line extending from the feed point of the antenna and the amplifier to a signal input of the broadcast receiver unit. The transmission line having a pair of conductors, for example, coaxial conductors. A manually operated switch is disposed in the transmission line for applying a DC voltage across the conductors, while a relay switch is operatively connected to the transmission line for changing a connection state of the amplifier to the transmission line in response to the voltage.
