Abstract

L'invention concerne un dispositif pour la transmission de signaux radioélectriques. Dans ce dispositif, pour transmettre des signaux radioélectriques entre des postes émetteurs et récepteurs mobiles 8, 9 se déplaçant dans un espace totalement blindé et comportant une station relais 1 et des stations d'extrémité 2, 7 reliées entre elles par l'intermédiaire de conducteurs doubles d'antenne 3 passant par des amplificateurs 4, les conducteurs doubles 3 sont constitués par des tubes métalliques parcourus par de l'eau de refroidissement. Application notamment à la transmission de signaux radioélectriques à l'intérieur de tunnels ou de galeries souterraines.
