Abstract
The present invention relates to single and twisted pair transmission line wires wherein the effective electrical diameter of the primary conductor is increased. This is accomplished by wrapping conductive foil or conductive foil laminated to a substrate layer onto a primary conductor with a diameter less than 20 mils wherein the foil is in contact with the conductor and has an outer insulating cover. This may be done by either spiral wrapping or by longitudinal wrapping around the electrical conductor. This invention provides a desired characteristic impedance along the length of the wire(s) and allows easy removal for standard termination and increased cut-through resistance.
