This paper describes the main electromagnetic characteristics of a radiating cable installed in a gallery. The emphasis is on the effect of the cable environment on the coherence bandwidth and on the delay spread of the radio channel. The direction of arrival of the waves inside the tunnel has also been deduced from the complex impulse response in order to optimize a method of localization of a mobile moving in the gallery.
