These VHF boat marine radios allow you to transmit easily from the wheel while keeping your focus on the waters ahead. They are for anglers of all ages and experience and packed with outstanding features and built compact and rugged to take the rigors of being out on the water. Most handheld models fit into your hand, have a large display that is clear and easy to operate. They are submersible for up to 30 minutes at five feet, have the waterproof level, and won’t give up no matter how wet it gets — whitecap splash, gusty spray, tidal wave, whatever, this radio can take it. They float to the surface, if you drop it in the water, and glow in the dark seals and power key allows you to find radio easily. Some models are switchable for short- and long-range communication — this is also a convenient way to save a little battery life. In most situations, the 1 Watt transmission power is all you need.
They cover all USA, International, and Canadian marine channels, keeping you up-to-date with all the latest marine activity and brings everything you’ll need on the water into one compact design. For some models, triple watch mode monitor also channels 16 and 9 for a signal while you listen to the currently selected channel (checking channels 16 and 9 for activity every 2 seconds). Some portable VHF radio models have additional accessories included – SMA flexible rubber antenna, rapid clip-on DC charger, lithium-Ion rechargeable battery, sturdy belt clip for maximum mobility.

FAQ
Do I need a license to operate a VHF radio?
In many countries, you need a license to operate a VHF radio on a boat. However, regulations vary. In the US, for example, you don’t need a license for domestic use, but you do for international waters.
What’s the difference between a handheld and a fixed-mount VHF radio?
Handheld VHF radios are portable, battery-powered units. Fixed-mount radios are permanently installed on a vessel, have higher power output, and are connected to the boat’s electrical system.
What is the range of a VHF radio?
The range depends on various factors, including antenna height, power output, and environmental conditions. Typically, handheld units have a range of 3-5 miles, while fixed-mount units can reach 20 miles or more.
What does DSC stand for, and why is it important?
DSC stands for Digital Selective Calling. It’s an important feature that allows for automated distress calls, including your vessel’s position if connected to a GPS.
How does antenna height affect VHF radio performance?
Antenna height is crucial for VHF performance. A higher antenna generally provides better range due to the line-of-sight nature of VHF transmissions.
What is Channel 16 used for?
Channel 16 (156.8 MHz) is the international distress, safety, and calling channel. It should be used for emergency communications and initial contact before switching to a working channel.
How do I make a distress call?
To make a distress call, tune to Channel 16 and say “MAYDAY, MAYDAY, MAYDAY,” followed by your vessel name, position, nature of distress, and assistance required. If equipped with DSC, press the distress button for 5 seconds.
What’s the difference between “Mayday,” “Pan-Pan,” and “Securité” calls?
“Mayday” is for life-threatening emergencies. “Pan-Pan” is for urgent situations not immediately life-threatening. “Securité” is for important navigational or weather warnings.
How often should I test my VHF radio?
You should test your VHF radio before each trip. Many areas have automated radio check services, or you can request a radio check on Channel 16.
My VHF radio isn’t transmitting well. What could be the problem?
Poor transmission could be due to several factors: low battery (for handhelds), damaged antenna, corroded connections, or being in a poor location (e.g., surrounded by metal structures).
How do I update my VHF radio’s firmware?
The process varies by manufacturer. Generally, you’ll need to download the firmware from the manufacturer’s website and follow their specific instructions for updating.
What is AIS, and how does it relate to VHF?
AIS (Automatic Identification System) uses VHF frequencies to transmit vessel information. Some VHF radios can receive or even transmit AIS data, enhancing navigational awareness.
Can I use my VHF radio to get weather information?
Yes, many VHF radios can receive NOAA weather broadcasts. In the US, these are typically on channels WX1 to WX9.
What’s a MMSI number, and why do I need one?
An MMSI (Maritime Mobile Service Identity) is a unique 9-digit number used to identify your vessel in DSC communications. It’s necessary for using DSC features and should be programmed into your radio.
Are there any new technologies on the horizon for VHF radios?
Yes, emerging technologies include software-defined radios, integration with smartphones, and enhanced data transmission capabilities.
Will VHF radios become obsolete with the advent of satellite communications?
While satellite communications offer global coverage, VHF radios remain crucial for short-range marine communications and safety. They are likely to remain a primary communication tool for the foreseeable future.
