Simrad Broadband 4G radome antenna

Beam Sharpening
The only dome radar in the world to employ beam sharpening. This unique function allows you to control the level of target separation, so you can see the sharpest images possible when you need them most.
0-36nm Range
Zero main bang and a large working range produce crystal clear target definition right from the bow of your boat and up to 32nm away.
Dual Range when used with NSE/NSO
Capable of displaying Dual Range radar combinations when combined with an NSE or NSO system all from the same single dome.
High Speed Mode
Select 48rpm for almost instant updating at less than 1nm.
Advanced Target Detection
Increased target detection with directional clutter rejection and sidelobe suppresion.
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 20 targets in dual range mode (requires a heading sensor).
Dual Guard Zones
Protect yourself from more angles.
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.
Ethernet Connectivity
Connect to an NSS, NSE or NSO navigation system with ease.
