A rectenna was a large dish-shaped sensor and communication array installed on a starship. Rectennas were commonly installed on YT-1300 light freighters such as Millennium Falcon, which possessed an ANq-51 sensor array computer and rectenna made by the Fabritech Corporation that included both active and passive sensors, powerful jammers, intership transmitters, and short-range target acquisition systems. The falcon's own rectenna was lost at the Battle of Endor and had to be replaced shortly after.
