A radiating transmission line system employs a pair of leaky coaxial cables which are spaced from each other and extend along a tunnel to propagate radio signals. The signals to be propagated are fed to both cables in such a manner that the signals in one cable are in antiphase to the signals in the other cable. This reduces attenuation of the signal in the cable.
