Underwater Loop Reception Phenomena and Techniques - and Appendix

Abstract

The underwater propagation of radio signals and the mode of operation of submerged loop antennas are briefly considered. Directional and nondirectional reception are discussed, and an omnidirectional loop circuit is presented. Study of the influence of submerged depth and iron cores on loop dimensions, and the consideration of boundary depths for effective reception, lead to a suggested omnidirectional loop system in which the loop structure is mounted on or suspended from a submerged buoy and is located within the boundary layer of long-distance reception.
