Simrad Broadband 3G radome antenna


  • Unrivalled Short-Range

    Superior short-range target discrimination allows clear identification of targets near your boat.

  • Crystal Clear Image

    Fantastic for tight manoeuvres in marinas or in conditions of limited visibility.

  • Automatic Clarity

    Proven Harbour and Offshore auto modes offer a simple solution that requires no tuning.

  • MARPA Target Tracking

    Track up to 10 targets (requires a heading sensor).

  • Dual Guard Zones

    Protect yourself from more angles.

  • InstantOn™

    Solid-state technology produces an immediate, accurate on-screen image unlike normal warm-up times associated with magnetron pulse radars.

  • Low Power Consumption

    Ideal for boats of any size, sail, cruise or fish.

  • Zero Radiation Hazard

    Safer than any other radar currently on the market and emitting less radiation than a mobile phone enable it to be mounted anywhere.

  • Quick Installation

    No reason to open the dome, no tune or zero mile adjustment and no radar-licensed technician required.

  • 0-24nm Range

    30% more range than the original BR24 Broadband Radar and zero main bang.

  • High Speed Mode

    Select 36rpm for almost instant updating at less than 1nm.

  • Ethernet Connectivity

    Connect to an NSS, NSE or NSO navigation system with ease.
