Abstract: A radiating coaxial cable includes an inner conductor, an electrical insulator located about a periphery of the inner conductor, and an outer conductor located about a periphery of the electrical insulator. The outer conductor defines groups of apertures spaced from each other a predetermined distance in the range of from about twice the longest operational wavelength of the cable to less than ten meters. The aperture groups are designed in such a way to excite a surface wave at low operating frequencies and a combination of surface and radiating waves at high operational frequencies.
