The first of these long-range primary radars was commissioned at Sydney Airport in September 1962. They served Australia’s capital city airports until the early 1990s. The Airways Museum's example is the Melbourne Terminal Area Radar (TAR) which was in service from 1966 to 1992. It was located on the north-eastern boundary of Melbourne Airport, alongside the Bulla Rd.

The magnetron, which generates the radar's microwave RF energy, is arrowed.

From the early 1970s, the long-range primary radars were supplemented by Secondary Surveillance Radar (SSR).

The equipment on display was replaced by a short-range (50 NM) primary radar and a long-range monopulse SSR at nearby Gellibrand Hill.
