Chain Home was the codename for the ring of coastal Early Warning radar stations built by the British before and during the Second World War. It was one of the first practical radar systems and the main component of the world's first integrated air defence system. The system otherwise known as AMES Type 1 (Air Ministry Experimental Station) consisted of fixed cable array antennae slung between three or four steel towers. The radar transmitted on the HF 12 m frequency band between 22-25 MHz depending on operational requirements. The installations were known as 'stations' and were designed to provide long-range detection of aircraft. This system had shortcomings in not being able to detect aircraft at lower altitudes and thus was used in conjunction with the Chain Home Low system, or AMES Ty

  • Chain Home was the codename for the ring of coastal Early Warning radar stations built by the British before and during the Second World War. It was one of the first practical radar systems and the main component of the world's first integrated air defence system. The system otherwise known as AMES Type 1 (Air Ministry Experimental Station) consisted of fixed cable array antennae slung between three or four steel towers. The radar transmitted on the HF 12 m frequency band between 22-25 MHz depending on operational requirements. The installations were known as 'stations' and were designed to provide long-range detection of aircraft. This system had shortcomings in not being able to detect aircraft at lower altitudes and thus was used in conjunction with the Chain Home Low system, or AMES Type 2, which could detect aircraft flying at minimum altitude level of . This was further refined by the addition of Chain Home Extra Low, which gave cover down to but at short ranges of only approximately . CHEL was in operation by 1943 under the designation Type 13 / 14. CHEL was the first RAF centimetric radar system working on a frequency of 10 cm rather than the 12 m HF band Type 1.
