MIL-A-23836, MILITARY SPECIFICATION, ANTENNA SYSTEMS, SUBMARINE, DESIGN, LOCATION, AND INSTALLATION, GENERAL SPECIFICATION (3 SEP 1963)., This specification covers the general mechanical and electrical requirements for design, and for location and installation on Submarines of antennas for electronic equipment, and is primarily for the use of antenna system manufacturers. Electronic equipment covered by this specification is primarily external to the pressure hull. In addition to the radiating elements (both active and passive), antenna systems within the scope of this specification consist of the radio-frequency transmission line from the connector at the inboard detecting or transmitting equipment to the outboard receiving or radiating element and all components which which serve to tune erect, protect or interconnect the antenna. The hydraulic system from the erecting mechanism back to the first distribution manifold is part of the system. Electrical control cables from the actuating equipment out to and including the outboard antenna components are part of the system. Functional parts of the submarine such as the snorkel tube and periscope which also serve as antenna masts shall conform to the requirements of their primary, purpose, suitably modified for subject multi-purpose use. The term system as employed within this specification refers to military operational function as a subsystem of a submarine rather than to electrical, electronic, mechanical and hydraulic equipment divisions. Antenna systems are essential for the safety and continued combat capability of the ship.
