WM-RBII Radar Beacon (RACON)

RBIIRACONS are receiver/transmitter devices operating in the maritime radar frequency bands (9 and 3 Ghz) that enhance the detection and identification of certain radar targets.

The WM-RBII is a second generation racon, using all solid-state electronics designed to meet with the recommendation and guidelines from IALA/IMO.

The WM-RBII is a frequency-agile racon and hence responds on the frequency on which they are interrogated. Upon receiving a pulse signal from a ship-borne radar, the WM-RBII transmits back a Morse-coded signal whose frequency is identical with that of the ship-borne radar, and leaves a clear signal on the ship’s radar display indicating its own position with precision.
