Abstract :
Leaky section radiating cables are the main type of radiating cables which are installed in tunnels to provide radiocoverage. In this paper we present the results from radiocoverage measurements that were conducted into a tunnel. The results of radiocoverage of the radiating cable are presented based on measurements for different heights and positions of a receiving antenna in the tunnel. A comparison between the coverage provided by the radiating cable and the directional antennas installed in the entrance of the tunnel is presented. Finally a statistical analysis of the fluctuations of the coupling loss due to the propagation into the tunnel is presented.
