The Confederation formed in 1978 to represent the rapidly growing TV aerial industry. With the switch from black and white TV viewing to colour the UK TV aerial industry grew dramatically as everyone in the nation had to replace their old VHF TV aerial with UHF. In the late 1980s the CAI extended its scope as the natural representative body for satellite dish installation when satellite viewing began its dramatic rise in popularity with birth of Sky TV. Today the CAI has membership categories for everyone from sole proprietor aerial and satellite installers, to the largest commercial system design and installation companies along with manufacturers and distributors who supply all the necessary equipment for signal reception and data networks. The CAI also welcomes applications from consultants and broadcast operators.
