CH18 Trerew, Cornwall.
CH = Chain Home was a set of radars that were started prior to WW2 and in 1939/40 covered the east coast of England, by 1945 they had been expanded to cover the whole of the British Isles.
The radar was an early form and when switched on it lit up like a row of searchlights. A plane flying towards the light is shown up on a screen and direction, height and numbers could be read out. But as the planes fly over the aerials they cross out of the light and then it was the job of the Observer Corps (later Royal Observer Corps) who were situated all over the country would then report their sightings and passed them on to the RAF and fighters would be scrambled and sent to intercept the boggies.
