The RM20 25W fixed-mount marine VHF radio is IP67 waterproof, has a NOAA Weather alarm, is high-volume, and is a VHF DSC marine radio with dual/Tri-Watch, which makes it the best radio for boats and cruise ships.
It is vital to have clear communication while on the water and Retevis kept that in mind when designing RM20. The speaker is placed on the front panel, without shielding, and the audio is crisp. High volume, up to 110dB; Supports external speaker with 3.5mm pin, and features a separate squelch knob to eliminate unwanted background noise such as wind and engines.
Built with a GPS receiver, simply power on and press DCS for 1 second, and your radio will instantly and accurately receive your GPS location no matter where you are. This feature is especially important in an emergency situation.
IP67 waterproof (1 m depth of water for 30 minutes) and Vibration drainage function(While pushing and holding [▲] and [▼], turn the power ON. “ VIB WATER " appears.)
The weather at sea can be very changeable, and NOAA broadcasts can help you up to date on weather trends and emergencies. This radio has 10 weather channels. When the weather alert function is on, 24-hour access to national All-Hazards and weather information on weather channels; NOAA Weather alarm Alerts you to nearby threatening weather.
It’s important that boaters use the correct channel when communicating on a marine VHF radio band. Channel 16 and 9 are very important common channels especially for recreational boats. The “16” key is for quick access to channel 16 and 9.
RM20 is a standard VHF DSC marine radio. In the event of an unexpected emergency, press DSC button and your MMSI and exact position will be sent to the Coast Guard and other vessels.
There is a separate “Emergency Alarm” button, press that button to make a distress call in emergency. The nearby shore station and other vessels with DSC equipped will receive this call, and it will alarm for quick rescue.
This compact radio is easy to be installed and easy to operate. The dot-matrix LCD screen allows you to read the parameters and settings easily and menu system with programmable soft keys gives you simplified functionality.
About Antenna
The special antenna for ship platform is encapsulated in glass fiber reinforced plastic, waterproof, and corrosion resistant; contains pure copper vibrator, has a long communication distance, is equipped with an adjustable fixed base, and can adjust the antenna angle by 180°; includes all maritime frequency bands and can be installed on the ship or outdoors.
1. FRP encapsulation, omnidirectional waterproof and corrosion-resistant, anti-ultraviolet, no cracking, waterproof, wind-resistant, strong sealing, suitable for harsh marine environments.
2. Using pure copper vibrator, the receiving sensitivity is high, the impedance is accurately matched, and the communication distance is longer.
3. The built-in fixture is easy to install, and the antenna direction can be adjusted by 180°.
4. Support maximum power: 100W gain: 3.5dbi.
