History of RF coax cable
RF coax cable is a particularly important part of today's RF and electronics scene. It is a component that could easily be overlooked with little thought of how it appeared. In the late 1800s there were a huge number of basic discoveries being made in the field of electricity. Radio, or wireless as it was originally called was not understood well, and the first transmissions were made in the 1890s.Some transmissions were made earlier but not understood.The first known implementation of coax cable was in 1884 when Ernst von Siemens (one of the founders of the Siemens empire) patented the idea, although there were no known applications at this time. It then took until 1929 before the first modern commercial coax cables were patented by Bell Laboratories, although its use was still relatively small. Nevertheless it was used in 1934 to relay television pictures of the Berlin Olympics to Leipzig. Then in 1936 an a coaxial cable was installed between London and Birmingham in the UK to carry 40 telephone calls, and in the USA an experimental coaxial cable was installed between New York and Philadelphia to relay television pictures.
With the commercial use of RF coax cable establishing itself, many other used the cable for shorter runs. It quickly established itself, and now it is widely used for both commercial and domestic applications.
