The antenna site above is part of Reynella, a city about 20 km South of Adelaide. The main antenna in front broadcasts simultaneously on 729 kHz and 891 kHz with 50 kW each.
The two other masts are used in case the main antenna fails. They operate on the same frequencies with the same power.
In both cases the radiation patterns are similiar. The differences of reception field strengths caused by the main antenna and the auxiliary masts are not more than 1 to 2 dB.
These are the coordinates of the main antenna:
35° 06' 14.04" S 138° 31' 7.32" E
