In which frequency band does a search and rescue transponder operate?

Official USCG Answer & Rule Citation

Correct Answer: Option B — 9 GHz

Search and Rescue Transponders (SARTs) are designed to operate in the 9 GHz frequency band, which corresponds to the 3-cm X-band radar spectrum. This specific frequency allows the SART to be detected by standard marine navigational radars, facilitating the location of survival craft during distress operations.
