DEVELOPMENT OF A FIXED ENCAPSULATED SUBMARINE ANTENNA FOR THE AN/BRD-4 AND AN/SRD-7 DIRECTION FINDERS.

Abstract

A radio direction finding antenna based on the crossed loop principle has been developed for submarine use covering the frequency range from 100 kc to 160 mc. The antenna uses no pressure dome and is encapsulated in polyurethane so that no air spaces exist within the antenna with the exception of a few reed relays. This report covers in detail the design and development during 1964 and 1965 and includes performance and evaluation data. Although shipboard trials have not been completed, performance (including environmental) of the antenna on a typical mast installation on a land site has been measured. Pressure tests of the antenna have been completed to 3000 psi. Information required for a submarine installation is provided, and recommendations for future designs based on this exploratory development model are provided. This equipment was developed for compatible operation with either the AN/SRD-7 or AN/BRD-4 direction finding equipment with appropriate goniometers or future use with phase and gain matched twin channel receiving equipment.
