Product Description

B&G 4G >Broadband >Radar is the third generation of its >FMCW (Frequency Modulated Continuous Wave) radome revolutionary >Radar technology that eliminates magnetrons and provides crystal clear images of your immediate surroundings.

B&G 4G >Radar brings 50% more range than the second generation 3G >Broadband >Radar and is compatible with all B&G Zeus and Zeus Touch Units. New revolutionary Beam Sharpening technology provides the sharpest possible >Radar images.

Broadband >Radar Guide describes how B&G reinvented >Radar.


  • For optimal Target Separation, >Broadband 4G >Radar is the world’s first dome >Radar to use Beam Sharpening, which significantly improves Azimuth Resolution (the effective horizontal Beam Width of the >Radar signal) equivalent to 3.5' open array >Radar.
  • Unparalleled short Range target discrimination - even at 1/32nm Range. Docks, Channel markers, moored vessel are displayed with clarity and separation.
  • No radiation hazard - radome safe to mount in any location.
  • Simultaneous Dual Range from 200' to 36nm & high speed rotation (up top 48rpm). Note Zeus2 only - not available on Zeus Touch
  • Minimum Range: 2m.
  • Optional Heading Sensor for Radar image plotter overlay (explained).
  • RADAR Fast Scan - 50% increase in rotation speed when Range is less than 1nm
  • Radar MARPA function (option) - Track up to 10 targets & display alarm CPA/TCPA conditions
  • Sidelobe & Local Interference Rejection - improves false target illumination
  • Sea & Rain Clutter: 3-5 times less than pulse radar
  • Complies with ISAF Offshore special reg 32.9.1.l.ii active >Radar requirement
  • Power: 12/24v 20w transmit(typical), 3.3w standby.
  • Frequency: X Band 9.3-9.4GHz
  • 13.5mm small diameter easy to route Antenna cable.
