Raymarine’s RD418D Digital Radome is the perfect choice for small boats looking to add radar capability to their onboard navigation. The RD418D is compact and lightweight so it can be mounted on the mast or radar arch of just about any small boat, RIB, powerboat or sailboat.

Inside the RD418D is a powerful 4kW transmitter which gives the radar the capability to detect targets out to a maximum range of 48 nautical miles. The RD418D also has amazing short range performance too thanks to its 8 pulse-width transmitter.

Using the RD418D couldn’t be easier thanks to Raymarine’s automatic controls for gain, sea clutter and tuning (Auto GST.) Simply turn on the system and let the system adjust itself automatically.

When connected to a Raymarine a, c e or gS-Series Multifunction Display, the RD418D brings to life advanced MFD features like radar/chart overlay, MARPA target tracking, guard zone alarms, and much, much more.

    Comments about Raymarine RD418D Digital Radome with 10m RayNet Cable:

    I recently added a 4kw radar to my Raymarine C120w Network display. I installed it myself with little trouble after finding the correct adapter to communicate digitally with my mfd.

    Having radar is a must, especially off the Washington coast crossing the Columbia River bar. I feel so much more confident navigating in low light or foggy conditions now with radar overlay on my chartplotter.
