EPIRB SART SAR-9 W

SAR-9

SART (9GHz Seach & Rescue Radar Transponder)

Posted in .

Samyung SAR-9 is a Radar Transponder, which is operated in 9.2~9.5 GHz(3cm) marine radar band. When a radar signal is received from a SAR craft, the SAR-9 automatically starts to transmit a response signal echoing to that Radar. SAR craft can identify SART s location on the radar screen with 12 in-line dots. Once activated, the SAR-9 will remain in stand-by condition for 96 hours followed by minimum 8 hours transmission.
