Antenna, especially for receiving television, radio and/or data signals, has impedance adapter and amplifier circuits forming unit operating as adapter circuit if amplifier stage fails

摘要

The antenna has an impedance adapter circuit (15) and an amplifier circuit (16) that together form a circuit unit whose operation in the event of the failure of the amplifier circuit corresponds to the operation of the impedance adapter circuit. Its operation in the event of non-connection to an electrical supply corresponds to the operation of the impedance adapter circuit.
