Comprehensive Awareness
The all-weather ONWA Radome keeps you aware of surrounding traffic, hazards, obstacles, and approaching weather. Navigate confidently in dense fog, rain, and low-visibility conditions. The Radome antenna perfectly blends compact size, lightweight design, and high performance. Choose the Radome antenna when space is limited or rigging restrictions apply. The HD Radome scanner offers reliable radar performance while consuming less power than magnetron-based open array scanners.
Energy Efficiency
The ONWA Radome radar is designed with energy efficiency in mind, consuming significantly less power than traditional magnetron-based open array scanners. This reduced power consumption is particularly beneficial for long voyages, helping to conserve energy and extend the operational range of your vessel.
Robust and Reliable Design
The ONWA Radome are built to endure the harshest marine environments. Their sturdy construction ensures durability and long-lasting performance, while their weather-resistant housings protect the sensitive internal components from the elements.
Easy Installation
Designed for easy installation, the ONWA HD Radome radar can be seamlessly integrated with your existing navigation systems.
It can be connected to our dedicated radar display and our KM series multi-functional chartplotters, providing versatile and comprehensive navigation support.
Radar Overlay on Charts
The KM Series allows radar data to be overlaid on nautical charts, combining visual navigation aids with real-time radar information. This feature enhances situational awareness by showing radar echoes on the chart, making it easier to correlate radar returns with charted objects.
Advanced Features
-
Gain Control: Built in Sea and Rain clutter algorithm for the best possible image in varying conditions.
-
Dual Range Scanning: Simultaneously monitor short and long-range targets, providing a comprehensive view of your surroundings.
-
Weather Overlay: Integrates weather data directly onto the radar display, helping you anticipate and navigate through adverse weather conditions.
-
ARPA Target Tracking: Utilize Automatic Radar Plotting Aid (ARPA) to track up to 40 targets, offering detailed information on their speed, course, and closest point of approach (CPA).
