EEVblog #569 - Tour of an Analog TV Transmission Facility

Ever wondered how they transmit your TV signal? David Kilpatrick from TXAustralia takes us on a detailed tour of the old decommissioned 10kW analog TV transmission system at the Artarmon facility in Sydney. It is still used to transmit digital TV. How it all works from the broadcaster video input to final transmission output up the 180m broadcast antenna. Plus some teardowns of the old equipment that's been used to transmit the Channel 7 TV signal in Sydney since 1981. Copper rigid coaxial lines, waveguides, filters, splitters, combiners, converters, transmission valve, power supplies and all the equipment necessary to transmit a 10kW analog or digital TV signal in a major city like Sydney.
