On a typical shipboard application, an Electromagnetic Radar like the ST-309L / I1 is used for navigation and collision avoidance. Operating in X-Band and S-Band frequencies, it complies with IMO SOLAS regulations to ensure safe maritime operations. This device requires regular maintenance to keep the vessel's radar systems operational: the magnetron should be replaced every 5,000 to 8,000 hours due to its limited lifespan, while the antenna bearing needs annual lubrication to prevent mechanical failure. Additionally, weekly performance monitor tests are required as per IMO standards, and an annual inspection ensures optimal functionality. Common issues include magnetron end-of-life after around 5,000-8,000 operational hours (with magnetron models), antenna rotation motor wear after over 30,000 hours, display backlight failure, heading marker drift, and water ingress in the waveguide due to poor pressure sealing. Keeping a spare magnetron on board can mitigate downtime during repairs.
