Abstract:
A wireless receiving subsystem operatively connectable to a broadcast receiver unit having a frequency tuner, comprising:an antenna having a feed point;an amplifier located essentially at said feed point;a transmission line extending from said feed point of said antenna and said amplifier to a signal input of a broadcast receiver unit, said transmission line having a pair of conductors;a first switch disposed in said transmission line for applying a DC voltage across said conductors; anda second double-throw switch arranged so as to connect said amplifier to said feed point and said signal input upon the applying of said voltage across said conductors by said first switch so that in one mode of operation said feed point is connected indirectly to said transmission line via said amplifier and in another mode of operation said feed point is directly connected to said transmission line, thereby bypassing said amplifier.
