Electromagnetic RadarMedium

On board ships navigating international waters, the S-Band and X-Band radar systems, commonly known as the S-76LTH model by Hyundai Welding Co., Ltd. (Pohang), are essential for maintaining situational awareness. These radars operate according to IMO SOLAS regulations, providing critical information on obstacles and weather conditions. Regular maintenance includes annual inspections, weekly performance checks mandated by IMO requirements, and yearly lubrication of the antenna bearing motor to ensure smooth operation. Crew members should be aware that magnetrons need replacement every 5,000 to 8,000 operational hours, and a spare part must be kept on board for quick replacements, as delivery can take up to three weeks.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
