Abstract

The device produces a connection between a transmitter (E) and an aerial (At), either by a first channel or by a second channel including the amplifier. First and second directive couplers are each shunted by a power diode short circuiting device. Depending upon the control of the two short circuiting devices the first and second couplers connect the transmitter and the aerial to the first channel or to the second channel. The device has two further couplers connecting the first two couplers to the second channel.
