ABSTRACT:
An improved device and technique for improving the reception of very low quency and low frequency transmissions in seawater. A loop antenna, wound on a ferrite core, is encapsulated in a water impermeable housing. Non-conducting elements are attached to the housing and extend outwardly therefrom to serve as barriers to conduction currents in the seawater. By varying the dimensions and number of the non-conducting members, the quality factor of the loop antenna can be increased to provide improved reception of VLF/LF signals.
