DETAIL SPECIFICATION
CABLES, RADIO FREQUENCY, FLEXIBLE AND SEMIRIGID
GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments
and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers flexible and semirigid cables with solid and semisolid dielectric
cores, with single, dual and twin inner conductors. Cables covered by this specification are primarily
intended for use as transmission lines to conduct energy in a simple power transfer continuously or
intermittently. In general, these cables are designed for low-loss, stable operation from the relatively low
frequencies through the higher frequencies in the microwave and radar regions of the frequency
spectrum. Cables may also be used as circuit elements, delay lines or impedance matching devices.
These cables are supplied under a reliability assurance program as specified in section 3.
1.2 Classification. Cables are of the following types (see 6.2
).
1.2.1 Cable types.
1.2.1.1 Flexible, coaxial single conductor. A flexible coaxial cable is constructed of a single inner
conductor covered by a flexible low-loss, RF dielectric core material, which is then surrounded by a
braided outer conductor(s), with the whole covered by a protective covering. In some cases this is
covered by an extra braided armor for use in extremely abusive applications. Each element of the cable
is designed to contribute to the requirements of the finished product.
1.2.1.2 Semirigid, coaxial single conductor. Semirigid coaxial cables are constructed of a single inner
conductor covered by a flexible low-loss RF dielectric core material, which is then surrounded by a solid,
continuous, metallic outer conductor.
