Chain Home Low (CHL) was the name of a radar system used by the RAF during WWII. The official designation was AMES Type 2 (Air Ministry Experimental Station). It was based on CD (Coastal Defence) and CA (Coastal Artillery) radar designed for army use. It was noticed that these were able to detect low flying aircraft and so led to the development of CHL for the RAF. It operated on a shorter wavelength than Chain Home, about 1.5 metres. Later in the war Chain Home Extra Low (CHEL) radar used centimetric radar and was often co-sited with CHL sites.
