A high-gain antenna was a piece of advanced communications technology aboard NASA's Mariner 2 space probe when it was launched in the mid-20th century.

A schematic of the Mariner 2 spacecraft depicting the location of the high-gain antenna was stored in the USS Enterprise's library computer database. This database was accessed by the Talosians in 2254. (TOS: "The Cage")
