Raymarine’s new HD Digital radome scanners combine the power and clarity of HD Digital signal processing with an ultra-compact scanner suitable for all types of vessels. Compatible with C-Series Widescreen, E-Series Classic, E-Series Widescreen and G-Series Multifunction Displays, these radomes offer a 256-colour radar display and the clearest, most lifelike radome presentation available from any radome scanner.
The RD424HD feature the same adaptive digital receiver technology found in our open array antennas. By adjusting automatically to changing environmental and sea conditions, the HD Digital radomes provide crisp, accurate contact echoes at short ranges, as well as outstanding long range performance up to 48 nautical miles.
Adaptive digital receiver automatically adjusts to changing environmental and see conditions for a dramatically clearer picture
