Heated-window antenna

摘要

A heated-window antenna is proposed, in which the output of VHF signals and long-wave, medium-wave and short-wave signals to be amplified is improved. The connections of the heating conductor arrangement (11) belonging to the heated-window antenna are connected to a battery (26) via a VHF output circuit (36) and a long-wave, medium-wave and short-wave output circuit (21). The VHF output circuit (36) has a band-filter characteristic, which transforms the antenna impedance into the optimum noise-matching impedance of the VHF amplifier (31), taking into account the input capacitance (38) of the long-wave, medium-wave and short-wave amplifier (33). <IMAGE>
