Device for transmitting information and/or instructions and/or a location between a movable unit and a supervision station, comprising a hollow tube (1) parallel to the path of the movable unit, forming a waveguide, an emitting face (2) of which is pierced with a network of apertures, the movable unit having two hyperfrequency emitting and/or receiving antennas (4, 5). The network of apertures on the emitting face of the hollow tube permits the transmission between these apertures and the emitting and/or receiving antenna of two signals distinct from the electric field, one for the transmission of information and/or instructions, and the other for measuring the speed and the position of the movable unit by detection of the presence of this second signal. Other devices relate to the application of such hollow tubes to an automobile toll station or a station for monitoring an enclosure which is dangerous for personnel. …IMAGE…
