Racal Electronics Ltd, radio communications and electronic instrumentation maker, of Bracknell.
1950 Racal Ltd was created to provide a consulting service for the planning of radio communications systems. The name was derived from the partners RAymond Brown and George CALder Cunningham
1951 Racal Aerotronics (later Racal Instruments) was established as a subsidiary to build equipment for electronics instrumentation.
The first factory was located at Isleworth, west London.
1954 Needing extra space, the factory was transferred to Bracknell.
Focus was on high frequency radio communications equipment. Racal won a Royal Navy contract to build and supply a variant of the American Collins Model 51-J Radio Receiver but they were not granted a license to build these sets by Collins Inc. Racal had to design and build a radio receiver from scratch. The result was the famous 'RA17' - in production from 1955 to at least 1973 - designed in cooperation with Dr. Trevor Wadley and utilising his Wadley Loop circuit.

1962 New R&D building equipped.

1983 Racal competed for one of the original licences to operate a cellular network in the UK, both it and British Telecom were successful. Racal established the Racal Telecom (now Vodafone) subsidiary.
1984 Racal bought Chubb, a security company that manufactured safes and locks.
1988 20% of Racal Telecom was floated on the London Stock Exchange. This would lead to the situation where Racal Electronics was valued at less than its shareholding in Racal Telecom.
1991 Sir Ernest Harrison (Racal Chairman) demerged Racal Telecom in October 1991 forcing a positive valuation on the rest of Racal (colloquially known in the City as "the rump"). Vodafone would later become the largest mobile network in the world and the highest valued company on the FTSE 100. Immediately following the demerger, Williams Holdings launched a takeover bid for Racal. The bid, valued at £740m, failed.
