In a system for launching RF energy as a traveling surface wave onto a single wire transmission line and causing such energy to be radiated away from the line at a downstream location, a series of window radiators of annular shape are spaced along the line, coaxial therewith, each for radiating a portion of the surface wave energy. Each radiator has a conductive component that causes decoupling and radiation of a portion of the RF energy, and a dielectric window that allows the remaining portion of RF energy to pass therethrough and continue, as an attached surface wave, downstream to a succeeding, similarly formed radiator where the decoupling and partial radiation occurs again. Thus, from the same surface wave transmission line system, it is possible to radiate RF energy from two or more discrete locations along the line.
