| Zusammenfassung: | A receiving antenna for submarines wherein tunnel diodes are inductively coupled to a plurality of ferrite rod by a coupling link. The tunnel diodes are back-biased by a biasing circuit to establish operation in the negative resistance region. Bias current and coupling are adjusted to provide cancellation of the major portion of the ferrite core losses and copper losses of the main turning winding. |
