A connector and coaxial cable interconnectable via axial compression upon a cylindrical section of a solid outer conductor of the cable. The cylindrical section may be formed in the cable by drawing a cable end into an interference fit between a sleeve and an outer conductor seat formed in the connector body. Alternatively, the cylindrical section may be formed in the outer conductor during cable manufacture and the cylindrical section retained between the outer conductor seat and a crimp ring radially deformed by an angled die face during axial compression. To increase flexibility of a straight walled cable, annular corrugations may be formed in the solid outer conductor with the cylindrical sections at each corrugation peak. The cylindrical section having a length of at least 3 millimeters or 4 times the corrugation depth.

An RF coaxial cable with clad conductors includes an inner tubular conductor having a first base layer formed of a relatively higher conductivity material, and a first bulk layer formed of a relatively lower conductivity material. The first base layer of higher conductivity material extends over an area greater than an area of the first bulk layer to form first margin regions composed of only the higher conductivity material. The first margin regions of the first base layer of the higher conductivity material are joined together to form the inner tubular conductor with only the first margin regions of the higher conductivity material being joined. Also included is a dielectric material surrounding the inner conductor, an outer tubular conductor formed in the same manner as the inner conductor. The first base layer of higher conductivity material of the inner tubular conductor faces outwardly toward the dielectric material and the higher conductivity material corresponding to the outer tubular conductor faces inwardly toward the dielectric material.

A corrugated coaxial cable including a core with at least one inner conductor and a highly expanded polymeric foam dielectric surrounding the inner conductor. This coaxial cable has a corrugated outer conductor closely encapsulating the foam dielectric. The corrugated coax cable is dimensioned to provide the cable with a velocity of propagation of greater than 90% of the speed of light.

A hanger for attaching a length of a transmission line, such as, a coaxial cable or a waveguide to a supporting structure, such as, a crossbar on an antenna tower, includes two gripping elements. The elements have posts and openings to facilitate aligning of them with respect to each other. The posts and openings are arranged so that the posts in one element fit into the openings of the other element to help align the two elements when they are placed around a transmission line. Once aligned, the two elements are brought toward each other until they snap together to form a clamping structure which loosely grips the transmission line. The clamping structure can then be slid to the desired location on the transmission line. A bolt or a screw is then inserted through the aligned bolt or screw openings in the two elements and through the supporting structure. Finally, the bolt or screw is tightened to securely clamp the elements to the transmission line and to attach the resulting hanger to the supporting structure.

A radiating cable of the foam dielectric type is provided with increased flame-retardant capabilities by provision of an inert barrier tape between an apertured, corrugated outer conductor and the external jacket surrounding the conductor. The barrier tape is composed of non-halogenated, self-extinguishing insulating material and is wrapped over the outer conductor in such a way as to completely cover the radiating apertures disposed thereupon. The barrier tape prevents the melting and bubbling of the dielectric foam outwardly through the radiating slots into penetrating contact with the external jacket when the cable is subjected to high-intensity flames, without significantly affecting the transmission characteristics of the cable.
