The radar coverage is 360 degrees and encompasses much of Bass Strait, Tasmania's northwest, central north and to a lesser extent, the northeast and the west coast as far south as Strahan. The coverage to the south is limited in range by the Central Plateau. In all this radar has proven to be an invaluable forecasting and monitoring tool. False echoes are sometimes viewed close in from the nearby pine plantations particularly in damp conditions. Anomalous propagation from Bass Strait cause similar echoes. Permanent echo suppression and swept gain characteristics take care of the majority of these.
