FAR-2137S – 30 kW S-band radar
FAR-2827S – High-performance marine radar for large vessels
FAR-3220S / FAR-3230S – Advanced X/S-band radar for SOLAS-compliant ships
Various models using S-band transmitters in the VisionMaster FT series
Some older models of JRC’s S-band commercial radars have been reported using this magnetron as a compatible replacement
Marine radar models with similar waveguide/flange and frequency specs may use MG5223 as a retrofit or OEM part
