Detailed description
Detailed description
The Raymarine Quantum 2 Q24D Doppler radar antenna (reference E70498) is an advanced marine detection solution. This radome unit, manufactured in Hungary, integrates Raymarine’s CHIRP pulse compression and Doppler technology for precise target identification. Designed for 12/24VDC power, it offers versatile network connectivity options via WiFi and Ethernet. Weighing 5.6 kg, the antenna is rated IPX6 for water resistance, ensuring reliable performance in demanding marine environments. This model is supplied without power or data cables, allowing for custom installation configurations.
Doppler Technology and Performance
The Quantum 2 Q24D Doppler radar antenna stands out for its ability to use the Doppler effect to differentiate moving targets from stationary ones. Approaching targets are displayed in red, while receding targets appear in green, enhancing situational awareness and safety. With an effective range of 0.0625 to 24 nautical miles, a maximum output power of 20W, and a rotation speed of 24 RPM, this solid-state radar delivers fast detection and clear images. Its 4.9° horizontal and 20° vertical beamwidth ensures detailed coverage. Raymarine’s CHIRP pulse compression technology provides excellent target separation (6 meters) and simultaneous short- and long-range detection, outperforming traditional magnetron radars in clarity and lower power consumption.
Integration and Comparative Advantages
The Raymarine Quantum 2 Q24D Doppler integrates seamlessly with compatible Raymarine multifunction displays (Axiom, eS, gS, a, c, and e series running Lighthouse II/3). Compared to the previous Quantum 1 generation, Quantum 2 adds Doppler target tracking, a key improvement for navigation and monitoring. Unlike magnetron radars, its solid-state design ensures instant startup, reduced power consumption, and no harmful emissions—particularly beneficial for sailboats and low-power vessels. Compared to competitors such as the Garmin Fantom or B&G Halo20+/24, the Quantum 2 Q24D offers a high-performance alternative within the Raymarine ecosystem, emphasizing installation simplicity (via WiFi connectivity) and clear Doppler navigation data. Its extended operating temperature range of -10°C to +55°C ensures robustness across varied conditions.
