Title: Loading coil assemblies for communications cables

Abstract: A loading coil assembly comprises a casing having discs at each end. At the inlet end a support disc is mounted on and spaced from the end disc and a plurality of assembled magazines holding loading coils is attached at one end of each magazine to the periphery of the support disc. A similar support disc interconnects the other ends of the magazines, the magazines extending in a circle about the casing axis. Further circles of magazines can be added by providing one or more annular rings attached to the end disc carrying the support disc, for attachment of the magazines at one end, and also interconnecting the other ends of the additional circles of magazines by annular rings. The conductors can be fed along spaces between adjacent magazines. The casings vary in size according to the number of circles of magazines.
