The Nobeltec 4kW 25" Radome adds important radar information to a system that already includes GPS and sonar-making Nobeltec one of the most comprehensive marine navigation systems today.

Performance Driven
The 4kW provides functionality that includes automatic controls for gain and sea clutter. The 4kW dome features a narrow 3.9 ° horizontal and 25° vertical beam width, which delivers accurate target acquisition and better penetration through rain and fog. It has a range of 36 nautical miles (nm). For fast and efficient presentation of radar signatures, raw data is processed within the radome and presented on a PC that has either Nobeltec Visual Navigation Suite (VNS)™ or Admiral Software. (Sold separately)

Easy to Use
The radar features automatic and manual sensitivity and tuning controls, including gain, sea clutter, and rain clutter - which allows boaters to spend less time tuning the unit and more time navigating. The unit also boasts selectable interference rejection, which mitigates the effect of nearby radar transmissions.

Cutting-Edge Technology
Once the 4kW radar is interfaced with either Nobeltec Visual Navigation Suite (VNS)™ or Admiral, it is possible to overlay radar images on the charts to help reconcile radar signatures with known objects. Users can view "radar only" or split the display for multiple views of radar and charting.

To aid in collision avoidance, the unit also offers Mini Automatic Radar Plotting Aid (MARPA*) capability, which allows boaters to track the bearing, course, speed and predicted closest approach (by both time and distance) of up to 10 targets.

*MARPA functionality requires Admiral Software and an optional heading sensor.

**Nobeltec suggests the Nobeltec Solid State Heading Sensor.
