High performance radomes

Day and night Raymarine HD Radomes keep you aware of surrounding traffic, hazards, obstacles, and approaching weather. Navigate confidently in dense fog, rain, and limited visibility. Radome antennas are the perfect blend of compact size, lightweight, and high performance. Choose a Radome antenna when space is a premium or restricted by rigging. HD Radome scanners deliver trusted radar performance while consuming less power than magnetron based open array scanners.

Notes

1 - C-Series Classic chartplotter displays are only compatible with analog radar scanners, discontinued.

All radars transmit electromagnetic energy at microwave frequencies which can be harmful, particularly to the eyes. For safety, we recommend that any radar be installed above head height, out of range of personnel and passengers. 

Radar scanners should be mounted as high as practical above the waterline. Radar operates as a line-of-sight device, so a high mounting position will give better long-range performance. The radar is also best mounted above the head-level of crew and passengers, to avoid mechanical danger and minimize exposure to electromagnetic radiation.

The requirements for installation and operation of Raymarine radars may be subject to individual licensing of the equipment, operator, or vessel. You are strongly encouraged to check with the requirements of the licensing authority of your national administration. Your local Raymarine dealer can also advise on local and national licensing requirements.

Raymarine radars are ideal for use on rivers and inland waterways due to their excellent long and short-range target detection characteristics. The radar scope can also be presented in a heading-up presentation with a 1/3 or 2/3 offset that gives the radar operator maximum look-ahead visibility in these kinds of waterways. 

In most cases, installing a new radar scanner will require the change-out of the radar scanner interconnect cable but there are exceptions to this. For example, Raymarine offers an adapter cable (A80308) that allows a Quantum or Quantum 2 radar to use the interconnect cable from any Digital or HD Digital radar scanner. Other options may be available. Please consult with your Raymarine installer or technical support for options. 

In most cases new Raymarine scanners will fit on mounts that previously held another Raymarine radar scanner. The mounting pattern for radar scanners has been standardized for many years. There may be mechanical exceptions to this if changing from a radome-style scanner to an open-array due to the larger physical size and weight.

Raymarine radars are excellent tools for monitoring the weather. They can readily detect rain squalls, thunderstorms, and other atmospheric precipitation at long distances. Detecting and tracking weather at long distances can enable you to avoid harsh weather and make your time on the water safer and more enjoyable. 

Radome-style radar scanners are often mounted to a sailboats main mast or foremast using a specially designed mast mount. The mount is typically rivited or bolted to the mast and offers a secure mounting point with excellent line-of-sight for the radar to operate. Optional guards are normally available to provide extra protection to the scanner from the impact of sails or rigging, if needed. These mounts are offered by Raymarine and from 3rd parties like Edson, Questus, ScanStrut, and SeaView

Raymarine radar scanners come with a standard 2-year warranty covering both parts and labour. If you register your newly purchased radar on Raymarine.com within 90 days purchase your warranty coverage is extended to 3 years at no additional cost.  

Most marine radar scanners are intended to be used with chartplotters or multifunction displays from the same manufacturer, with some small exceptions. Raymarine’s Quantum radar is compatible with the Orca Core 2 navigation system, as well as the The Q Experience Q2 Display
