Rectenna

A rectenna (short for rectifying antenna) was a type of dish-shaped sensor installed on a starship. The Millennium Falcon, a modified YT-1300 light freighter owned by Han Solo, was equipped with a round military-grade rectenna at the time of the Galactic Civil War. By the time of the First Order–Resistance conflict, however, the Falcon was equipped with a rectangular model.
