Multiport cable choke
First Claim
1. In combination, a plurality of electromagnetic wave transmission lines each interconnecting one group of electrical apparatus and another group of electrical apparatus, and at least one multiport choke means for preventing buildup of undesired radio frequency currents along the external portions of said wave transmission lines, said multiport choke means comprising a single core having a plurality of windings of the same number of turns adjacently wound on said core in the same direction, said windings each comprising an electrical conductor means with a shield member, each of said windings being continuous with a corresponding one of said wave transmission lines, said multiport choke means further including a direct electrical connection adjacent said core between said choke shield members at each end of said choke windings.

Abstract
A unitary broadband high impedance isolation section for a plurality of cely spaced antennas as well as other electrical apparatus wherein the respective separate coaxial cables feeding the antennas and the shielded multi conductor cable for the other electrical apparatus are wound in the same direction on a common core and have the same number of turns, with the shields or outer conductors of all the cables being respectively connected together at the beginning and the end of the windings. The multiport cable choke thus configured can be provided with respective connectors at each end of the choke for facilitating ease of installation into the electrical system, that is, a single multiport cable choke can be inserted in the feed lines of multiple antennas and other electrical equipment simply by means of making suitable interconnections by way of the connectors on both sides of the multiport cable choke assembly. Further, the multiport cable choke can be contained in a suitable dielectric housing enveloping the common core and the cable windings and the connectors can be mounted in this housing.
