Radio/Stereo Noise Filter: Description and Operation

Wave trap / radio reception

Radio reception

Wave traps are required on the supply lines for the purpose of using the conductors of the rear window defroster for radio reception purposes. The wave
trap of the positive supply consists of a positive input and two outputs for the two heating sections of the rear window. A wave trap is also connected to
each of the connections of the two heating sections to ground.

Wave trap

The wave traps prevent the high frequency active aerial currents flowing via the positive or ground terminal. The wave traps also reduce conducted
interference from the rear window supply.
