RAYMARINE Radome antenna RD418HD Digital

The HD open array scanner has an output power of 4kW, with a maximum range of 72 nm and a power consumption of 46 W (9 W Standby)

 

Main characteristics:

The HD digital radar antenna allows the simultaneous display of two radar images with different display area (Dual Range). They also have a high-speed mode (48 rev/min instead of 24 rev/min), which is automatically activated when nearby fast targets are to be displayed. Other advantages of the HD digital antenna: automatic readjustment at changing weather conditions, quick digital processor and a new flock of birds mode.

Suitable for 12 and 24 V power supplies. Compatible with the C-series Widescreen, E-series Widescreen, E-series Classic and G series. Not compatible with the older C-series. Dimensions: Ø 52.1 cm, height 24.7 cm.
