The RBM4 is a latest-generation (frequency-agile) Radar Beacon, which works in the marine X and S radar bands, providing an important information to mariners under whatever meteorological conditions

The RBM4 incorporates advanced electronic technology components of radar systems, applied to navigation aids, such as programmable logic and flexible circuit antenna assemblies.

The Racon actively answers all active radars in the vicinity with a user programmed Morse code which identifies its location by appearing on the radar display.

Designed according to IALA Recommendations and IMO Standards.
