In view of the nature of the signals transmitted back to the station (high degree of focusing and high frequency), earth stations for SIGINT satellites need only small antennae.

In the case of very small earth stations, which operate in the V-band and whose signal, by virtue of the high frequency, can be focused even more strongly than those in the Ku-band, antennae with a diameter of between 0.5 and 3.7 m are adequate (e.g. VSATs from EUTELSAT or INMARSAT).

Pine Gap has 18 satellite antennae, one with a diameter of roughly 30 m and another with a diameter of roughly 20 m. According to official sources, and information provided by various authors, since its inception Pine Gap has been an earth station for SIGINT satellites.
