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 coaxial cable having coaxial inner and outer conductors which are separated by a helix of solid dielectric material. The helix extends through the annular space between the inner and outer conductors, and the helix is wound around the inner conductor. The inner edge of the helix engages the inner conductor and the outer edge of the helix engages the outer conductor. The outer edge of the helix forms multiple notches along the length of the helix, and the body of the helix is hollow.
