ABSTRACT:
A method of manufacturing leaky coaxial cable by winding conductive tapes around a core to provide apertures of a certain shape, number and density. By varying the width of one or both tapes the aperture distribution is varied thereby altering the coupling of the cable when used in a detection system. A graded cable showing such varying coupling can be used to compensate for cable attenuation losses and other variables.
