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

The RBM4 benefits from the latest electronic technologies like field programmable timers. 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.
