Signal station

sometimes called a 'Y-station'
A place used to watch for, or intercept, signals of an enemy attack. This could be Roman or Medieval tower from which a view could be obtained and a signal sent, by a beacon, flags or telephone. Alternatively, it could also be where radio signals were intercepted, (covertly received), during World War I so as to plot the movements of ships, aircraft and airships by taking a bearing, (using another station's bearing), and using triangulation. Such a 'Y-station' was based at Cullercoats seafront, (Tyne and Wear). In both cases defences could be readied and the alarm raised.
