Triax and High-Definition Video

Triaxial cable, coaxial cable with dual isolated shields, dates back to the 1940s. Philips experimented with triax-based cameras in 1972 to 1973 using 50Ω triax and N-type connectors. Kings Electronics produced a high-power 50Ω triax connector for the U.S. Navy around the same time. In mid-1975, Dave Elliott of ABC and Fred Della lacono of Kings Electronics discussed the idea of using triax cables, and and the “triloc” connector was born. This system was first tried at the Dorado Open Golf Tournament, Miami, FL., in 1975 and became the de facto camera standard by the time ABC produced the Olympic Games in Innsbruck, Austria, in 1976. The use of triax allowed a small cable of a half inch or less to run multiple signals. It replaced the huge cables, such as TV-81, which were very difficult to manage and impossible to repair. It is no surprise that triax became an international standard for professional video camera applications.
