Abstract :
An earlier analysis is extended to allow for the influence of ohmic losses in the external dielectric jacket of a coaxial cable that has a circumferential slit in the outer metal shield. It is found that when the loss tangent is greater than zero, the radiation pattern is modified, particularly at angles near the axis of the cable. The external surface wave is then also attenuated.
