At sea, it is essential to have the appropriate radio communication equipment by your side for your crew’s safety. Today, ships have a variety of communication devices to choose from, each with its own advantages and disadvantages. Find what you need by exploring some of the common types of marine radios available at Tecomart, your trusted wireless communications provider since 1994.
Very High Frequency (VHF) Radio
Very High Frequency (VHF) Radio. It is one of the most common and versatile marine communication devices onboard ships. VHF can be used for:
- Sending distress and safety signals
- Ship-to-shore communications and other land calls
- Navigation
- NOAA Weather Channel
One of the limitations of VHF is that it can typically only reach. That’s it up to 25 miles. This still makes it a reliable option for any vessel, but other options, such as single sideband (SSB) radios, have a much longer transmission range.
The Marine VHF unit can be mounted on a tabletop or other flush surface, like the ICOM IC-M330, or used as a handheld unit, like the standard Horizon HX210 (pictured). When choosing a VHF, look for additional features that will benefit your crew, such as the GPS receiver on the Icom IC-M330G.
Single Sideband (SSB) Radios
Single-sideband (SSB) radios use radio frequency (RF) waves to enable communication over long distances (25 miles or more). Low to medium-frequency transmissions can typically cover distances of 50 to 150 miles (considering weather and other conditions), while high-frequency transmissions can cover up to several thousand miles.
Devices such as the Icom IC-718 (pictured) and IC-M710 allow you to stay in touch with key personnel ashore and on other ships, even on the most remote voyages. However, they require slightly more complex installation than VHF equipment. SSB radios require proper grounding installation to support signal broadcasting and long antennas with different tunings to accommodate different frequency bands.
NAVTEX
If maritime radio communications equipment is defective or delayed, it is important that other means of maritime communication are available. NAVTEX (sometimes Navtex or NavTex) is a direct printing service that helps ships receive emergency alerts regarding navigation, weather, and even maritime safety.
NAVTEX receivers, such as the Samsung ENC SNX-300 (pictured), can typically receive both international and local channels and provide more comprehensive coverage, but within 200 miles of the coast. Bonus features to look for in a NAVTEX device include whether it is GMDSS compliant, which covers more comprehensive security.
GMDSS
The Global Maritime Distress Safety System (GMDSS) is a worldwide system for automatic distress signal communication at sea and can take the form of both fixed and handheld radios for survival craft. Masu. GMDSS includes the following systems to ensure crew safety:
- Alerting other ships or shore authorities in an emergency
- Coordinating search and rescue teams or locating a ship
- General or safety-specific broadcasts
- Bridge-to-bridge communications
GMDSS Typically, the system also provides redundant options for power supplies and emergency alarms. Its requirements and regulations do not apply to vessels of less than 300 gross tonnage and recreational vessels. Tecomart offers several wireless communication devices that meet GMDSS requirements, including the onboard JRC JHS-800S (pictured) and the Samsung ENC SRG-1150DN/1250DN/2150DN. We also offer handheld radios, such as the Icom IC-GM1600E, for emergency and survival vehicles.
