The RAF station at Northam came into operation in 1941 and was a Chain Home station – able to detect incoming high-level aircraft at long ranges. The station would have comprised two pairs of steel transmitter masts (325 ft.high) with a curtain array slung between each pair, two transmitter blocks (protected buildings in which radar personnel worked) two timber receiver towers (240ft high), two receiver blocks, and other necessary ancilliary structures such as a standby generator house, air-raid shelters, defence positions and guard posts. The Station ceased to operate in 1944.
