Coupling Between Antennas at Intermediate Frequencies

Abstract

Naval personnel have observed that coupling exists between various intermediate-frequency antennas and that this coupling produces serious effects if the coupled antenna system (including antenna loading coil) is near its resonance frequency. The general procedure used to avoid these coupling difficulties was to be sure that no two transmitter-antenna systems were tuned to nearly the same frequency. This can be accomplished by grounding or opening all antenna systems that are not in actual use. By following the above simple precautionary measures, the detrimental effects of coupling between transmitting antennas at the intermediate frequencies have been avoided.
