UNDERGROUND RADIOTELEPHONIC TRANSMISSION BY RADIANT HIGH FREQUENCY CHANNEL
UNTERIRDISCHE FUNKUEBERTRAGUNG MIT ABSTRAHLENDEN HOCHFREQUENZLEITUNGEN
In long subways, such as underground railway tunnels, radiant high frequency channels are necessary for sending the electrical signals covering conversations between mobile transmitters and receivers, and to transmit and receive them through the split armature of these radiant channels. For such radio-telephonic transmission, particular use is made of metric waves and, as regards construction, several solutions are possible. The authors present the multiple- channel radiotelephonic installations of the Hanover Underground, which have proved their worth.
