Abstract : For the reception of VLF waves, ferrite rod antennas are used which are usually coupled with the preamplifier input via a transducer. Relations are derived which permit the optimum dimensioning of antenna inductance and transducer in order to attain as high a signal voltage as possible. The noise behavior of the input stage is taken into consideration in a suitable adaptation. (Author)
