Key features and main functions
Marine radios are specifically designed for maritime environments. Alongside clear voice transmission, the main focus is safety at sea. These devices operate in the internationally standardised marine VHF frequency range, enabling ship-to-ship communication and contact with coast stations or harbour authorities. In emergency situations, the integrated DSC distress function is crucial. With a single press, a digital distress call can be sent, automatically transmitting the vessel’s identity and – on GPS-enabled models – its position.
| Marine VHF frequency range (156–162 MHz) | Standardised frequencies for communication between vessels and coast stations. |
| DSC distress function (Class D) | Digital emergency alert system for rapid contact with rescue services. |
| ATIS support | Identification system for radio communication on inland waterways. |
| IP67 / IP68 waterproof rating | Protection against rain, splashes and temporary immersion. |
| 1–25 W transmission power | Depending on the device type for different communication ranges. |
| GPS receiver (model dependent) | Transmits position data for distress calls or navigation. |
How to choose the right product?
- OKDefine your usage area: inland and coastal waters have different requirements for ATIS and DSC functions.
- OKChoose the device type: portable marine VHF radios are ideal on deck, while fixed radios are permanently installed.
- OKCheck waterproof rating: IP67 or IP68 devices are essential, especially for open boats.
- OKReview emergency features: DSC distress buttons should be easy to access and operate.
- OKEasy to use on board: large buttons, backlit displays, and intuitive menus are key in rough conditions.
- OKPlan installation and power supply: transmission power, antenna position and energy must match your vessel's.
- OKCheck visibility and durability: floating designs and corrosion-resistant materials improve safety at sea.
