SF-71 / C1

Navigational radars are essential for safe and efficient shipboard operations, providing critical information to captains and crew. The SF-71 / C1 radar operates with X-Band and S-Band frequencies, meeting IMO SOLAS requirements, ensuring compliance with international maritime safety standards. This electromagnetic radar system is designed to withstand the rigorous conditions at sea, but common issues can arise over time. For instance, magnetron end-of-life typically occurs after 5,000 to 8,000 operating hours on magnetron models, and the antenna rotational motor may experience bearing damage after 30,000+ hours. Other common failures include display backlight failure, heading marker misalignment, and moisture ingress in waveguides due to compromised pressurization. To mitigate these issues, it is recommended to keep a spare magnetron on board for magnetron models, with a lead time of 1-3 weeks from Hyundai Welding Co., Ltd. (Pohang). Regular maintenance practices are crucial: the magnetron should be replaced every 5,000-8,000 hours, and the antenna bearing should be lubricated annually. Additionally, weekly performance monitor tests, as required by IMO, and annual inspections are essential to ensure optimal operation of the SF-71 / C1 radar system.
