B&G 4G Broadband Radar Kit
Broadband 4G™ Radar - Features
| NEW Beam Sharpening Broadband 4G™ Radar is the only dome radar in the world to employ beam sharpening, which allows you to control the level of target separation, so you can see the sharpest images possible when you need them most. |
|||||
|
NEW More Range |
True Motion Display Easily distinguish moving targets from land with NSS, NSE and NSO. |
||||
| NEW Dual Range Capable of displaying Dual Range radar combination when combined with an NSE or NSO system. Monitor targets from 200 feet to 32nm from a single dome. |
InstantOn™ Solid-state technology produces an immediate, accurate on-screen image unlike normal warm-up times associated with magnetron pulse radars. |
||||
| New High Speed Mode Select 48 RPM* for almost instant updating at less than 1nm *48rpm currently available on NSE, NSO and Zeus units only |
Low Power Consumption Ideal for boats of any size, sail, cruise or fish. |
||||
| MARPA Target Tracking Track up to 10 targets. Track up to 10 targets as standard or up to 20 in Dual Range mode with independent control. |
Automatic Clarity Proven auto harbour and offshore modes including directional clutter rejection. |
||||
| Quick Installation No reason to open the dome, no tune or zero mile adjustment, and no radar-licensed technician required |
Extremely Low Emissions Safer than any other radar currently on the market and emitting less radiation than a mobile phone allowing it to be mounted anywhere. |
||||
| Dual Guard Zones Protect yourself from more angles |

Broadband 4G™ Radar
Broadband 4G™ Radar delivers 50% more true range than Broadband 3G™ Radar. Now you can see crystal clear targets up to 32nm away and inside strong storm cells more than 17nm away. See comparison table below for typical maximum distances that hard targets can be seen in good propagation conditions.
