Marconi rotating beam transmitter at Inchkeith, Firth of Forth, Scotland. This
Marconi rotating beam transmitter at Inchkeith, Firth of Forth, Scotland.
This revolving wirelss beam apparatus projects a horizontal ray of short wireless waves which sweeps round the horizon in about 2 minutes sending out distinctive signals indicating the direction in which the beam is pointing at the moment. A vessel desiring to know its hearing in relation to the lighthouse only requires to note on a short wave received at each revolution of the beam. This indicates absolutely the bearing of the lighthouse because only on that definite bearing can that distinctive signal be transmitted by the apparatus.
