HD Color Radomes are ideal when power is at a premium and mounting space is limited or restricted by rigging—excellent for sailboats, RIBs and smaller powerboats.

Raymarine’s HD Color radome scanners combine the power and clarity of HD Color signal processing with an ultra-compact scanner suitable for all types of vessels. These radomes offer a 256-color radar display and the clearest, most lifelike presentation available from any radome scanner.

The RD418HD features the same adaptive digital receiver technology found in Raymarine open array antennas. By adjusting automatically to changing environmental and sea conditions, the HD Color radomes provide crisp, accurate contact echoes at short ranges, as well as outstanding long-range performance up to 48 nautical miles.

Radome packs include 10m Raynet™ digital radar cable. Digital Radar Extension Cables available. Compatible with all third generation c-Series/e-Series, C-Series/E-Series Widescreen, E-Series Classic and G-Series displays.

Key Features

  • SeaTalkhs connectivity and Raymarine's Auto GST technology provides enhanced small target returns and eliminates clutter caused by rain and sea conditions automatically through your multi-function display
  • Adaptive digital receiver automatically adjusts to changing environmental and sea conditions for a dramatically clearer picture
  • 256 color multi-level target display with selectable color palettes
  • Bird Mode automatically optimizes the receiver for detecting sea birds above schools of fish
  • Dual-range mode allow you to monitor both long and short ranges simultaneously with a single scanner and display
