Which statement is NOT true regarding the SART?

The statement regarding the SART, which is accurate, is that it is a device designed to enhance the visibility of a life raft or distressed vessel to nearby rescuers. It operates by responding to an X-band radar's interrogation signal and then transmits a distinctive signal on its own.

The correct detail about operating frequencies indicates that a SART operates on a frequency that does not align with "6 GHz"; rather, it functions at "9 GHz." This capability allows the SART to be effectively detected by a vessel's X-band navigational radar, which is critical for search and rescue operations at sea.

Furthermore, the SART transmits a distinctive 12-blip signal, which helps rescuers easily identify its position on their radar screens, enhancing the chances of a timely rescue. This feature, combined with responding to radar interrogations, makes SART an invaluable asset in maritime safety. Understanding these specifics about SART's function and operational frequencies is crucial for ship operators and crew engaged in safety measures under the GMDSS guidelines.
