Royal Australian Air Force (RAAF) High Frequency Direction Finding Station

The Julia Creek facility consisted of two concrete buildings. One was a rectangular, reinforced concrete room that housed a generator plant that supplied power to the DF equipment and the barracks which were situated south of the generator room. The receiver console was housed inside a round concrete building, referred to as the 'set room', or 'round house' which stood about 200 metres north-west. The set room was originally equipped with four vertical aerials, referred to as a Marconi-Adcock Aerial System. Initially four trenches were dug, each 60 metres long in the form of a cross with a 7 metre high aerial in each corner. Cables were placed in the trenches, meeting under the centre of the round house. A length of heavy copper wire was laid out in the form of a circle connecting each aerial and when completed was covered with a layer of soil.
