A Communication Antenna System for Class SS-487 Guppy Submarine
Abstract
A high-frequency antenna system adapted to the Class 487 Guppy submarine is presented. The broad-band sleeve antenna for this system uses the superstructure of the submarine at the conning tower location as the sleeve element, while the upper radiator dimensions is indicated and three representative whips are studied in detail. Impedance characteristics are improved by using a suitable transformer. One of the transformed antennas maintains a SWR of better than 0.3 over the frequency range 5.2 to 15.2 Mc, and better than 0.5 from 5.7 to 10.0 Mc. Radiation patterns in the vertical plane are shown for this antenna. The availability of an effective broad-band antenna makes it possible to consider the design of a comprehensive communication system for submarines. A tentative system employing Common Antenna Working units and a specialized filter, permitting simultaneous medium- and high-frequency transmission and reception, is outlined. This report completes one phase of the general problem on shipboard antenna development. Work is continuing on related phases.
