A method of producing a leakage graded coaxial cable having a braided shield, in which ends of the shield wire are dropped as braiding progresses. Gaps in the shield having progressively increasing size are produced through which the radio frequency field leakage occurs, which facilitates providing a constant radio frequency field around the cable. The cable is coated with a jell flooding agent prior to extrusion of its protection jacket, which fills the interstices and gaps of the shield, and solidifies to a waxy, semi-resilient consistency. The resulting cable can be coiled and flexed, maintaining its shield reliability, and rejects water and fluids in case pinholes in the jacket occur.

A method of making a leaky coaxial cable comprising: (a) preparing a conductive axial wire covered by an insulating dielectric, (b) progressively braiding a conductive braid shield around the dielectric, and (c) dropping ends of the braid according to a predefined schedule for successive lengths of the braid shield, to produce progressively larger gaps in the braid shield as the ends are dropped whereby graded leakage of signal carried by the cable is facilitated. A method as defined in claim 1 including the further steps of covering the braid with a flooding agent, covering the flooded braid with an insulating protective jacket, and causing the flooding agent to solidify.
