MULTIPORT CABLE CHOKE

摘要

MULTIPORT CABLE CHOKE A unitary broadband high impedance isolation section for a plurality of closely 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.
