Woodside Omega Transmitter (station G, now Woodside VLF transmitter) near Woodside, Victoria, Australia was an Omega transmitter that used an umbrella antenna carried by a 432 metres (1,417 ft) tall grounded lattice steel guyed mast. Unlike many of the other Omega Transmitters, Woodside was not a "hot tower," that is, one which is insulated from a ground connection by large ceramic insulators that support the entire weight of the structure. Rather, the tower was electrically insulated from the topmost guys which served as the radiators, similar to the metal radials of an umbrella without cloth covering. The mast simply supported the downward sloping guy wires which are the active elements. The guy wires were also used to hold the tower itself in place. This mast was the tallest structure in the southern hemisphere. Construction of this station was originally planned to be built in New Zealand but after protests from anti-war protestors it was built in Australia, although not without controversy. The tower was officially opened in October 1982, but had been operating for 3 months prior to that, with the first broadcast at 10am on the 16th of August, having taken 3.5 years to construct.
