Ship crews rely on reliable radar systems for navigation, collision avoidance, and maritime situational awareness. The Hyundai Welding Co., Ltd. (Pohang) S-7028.F is an X-Band / S-Band electromagnetic radar system that meets IMO SOLAS requirements. This radar system has received DNV approval. While generally durable, the S-7028.F can experience common failures such as magnetron end-of-life after 5,000-8,000 operating hours (on magnetron models), antenna bearing motor bearing damage after 30,000+ hours, display backlight failure, heading marker drift, and waveguide moisture ingress due to disrupted pressure. To mitigate these potential issues, Hyundai Welding Co., Ltd. (Pohang) recommends keeping a spare magnetron on board for magnetron models (lead time: 1-3 weeks) and performing annual antenna bearing lubrication. Regular maintenance includes weekly performance monitor tests (as required by IMO) and an annual inspection.
