The coil generally employed for wireless telegraphy is technically known as a ten-inch coil—i.e., a coil which is capable of giving a ten-inch spark between pointed conductors in air at ordinary pressure. The construction of a large coil of this description is a matter requiring great technical skill, and is not to be attempted without.

In he began experimenting with wireless telegraphy. The apparatus he used was based on the ideas of the German physicist, Heinrich Hertz. Marconi improved Hertz's design by earthing the transmitter and receiver, and found that an insulated aerial . The Wireless Telegraphy Act while acknowledging the existence of wireless telegraphy, brought all broadcasting matters in Australia under the control of the Federal Government. In , the first official Morse code transmission in Australia was conducted by the Marconi Company between Queenscliff, Victoria and Devonport, Tasmania. .
