When it comes to communication at sea or in remote areas, a VHF radio is an essential tool that can ensure safety and reliability. Whether you’re a sailor, an aviator, or someone who spends a lot of time in remote areas, choosing the best VHF radio can make a big difference.
In this blog, we’ll walk you through what to consider when buying a VHF radio so that you can make an informed decision.
What is a VHF Radio?
Before diving into the details of what to consider when buying one, let’s first understand exactly what a VHF radio is. VHF stands for “Very High Frequency,” and a VHF radio operates within a specific radio frequency range.
These radios are mainly used for communication in areas where cell tower signals are weak or unavailable, such as on boats, airplanes, or remote locations. VHF radios are especially popular in marine environments because they allow for clear communication over water, which is crucial for the safety of crews and passengers.
What is a VHF Radio Used For?
Now that we know what a VHF radio is let’s answer the question, “What is a VHF radio used for?” VHF radios are mainly used for long-range, unobstructed communication. They are most commonly found in boats, allowing sailors to communicate with other vessels, marinas, and coastguards. VHF radios are also used by search & rescue workers, aviators, and people working in remote locations.
They can be very helpful in maintaining contact when cell towers are out of reach or out of operation. In essence, they provide reliable communication for various activities, from outdoor adventures to professional use.
In emergencies, a VHF radio can be a lifesaver by enabling a vessel to send distress signals and receive help.
VHF Radio Range
One of the first things people regularly ask about VHF radios is, “What is the VHF radio range?” Or, just how far can you communicate with a VHF radio? The range of a VHF radio largely depends on factors like effective radiated power (ERP), antenna height, environmental conditions, and obstacles like buildings and trees. Generally, VHF radios work on a “line of sight” principle, meaning that the higher the antenna and the fewer obstacles between you and the person you’re communicating with, the farther the range will be.
Most handheld VHF radios have a range of about 5-8 miles (8-13 kilometers) in normal conditions, while high-powered, fixed-mount VHF radios with elevated antennas can reach ranges of up to 20 miles or more. However, factors like mountains, buildings, or even the curvature of the Earth can reduce this range. That’s why having a high antenna or being in an open area like a lake or the ocean can significantly boost the VHF radio range.
Types of VHF Radios
Handheld VHF Radios
Handheld VHF radios are portable and battery-operated, making them ideal for smaller marine vessels, hiking and foot patrols, camping, or as a backup communication device. Handheld VHF radios are convenient because they are easy to carry and store. Bluetooth® capabilities for accessories add even more to the convenience of portables.
However, their power is usually limited to 5 watts, which means their range is shorter compared to fixed-mount radios. They are perfect for personal use and shorter-range communication.
Some excellent VHF portable options include the Motorola Soutions MOTOTRBO™ R7, the MOTOTRBO™ R5, the MOTOTRBO™ R2, and the MOTOTRBO™ CP 200D.
Fixed-Mount VHF Radios
A fixed-mount VHF radio is a mobile radio with a VHF antenna mounted on a solid antenna plane or “ground plane.” You’ll find fixed-mount VHF radios on boats, airplanes, trucks, and automobiles, as well as atop elevated towers.
Fixed-mount VHF radios usually have more power (up to 25 watts), giving them a much longer range compared to handheld radios. They are ideal for larger marine vessels and other vehicles that tend to travel further from their base of operations.
When choosing between handheld and fixed-mount VHF radios, consider the size of your vehicle, how far you plan to travel, and how much space you have for installation.
Some excellent VHF fixed-mount mobile options include the Motorola Soutions MOTOTRBO™ XPR 5550e Mobile, MOTOTRBO™ CM300d Mobile, and the the MOTOTRBO™ CM200d Mobile.
Important Features to Consider
Waterproof Rating
Since most VHF radios are used in marine and outdoor environments, they must be able to withstand water. Look for a marine VHF radio that is rated IP67 or IP68, which means that this marine VHF radio can survive submersion in water. This is especially important for handheld marine radios that may be exposed to splashes, rain, or even accidental drops into the water.
Battery Life (for Handheld Radios)
Battery life is crucial when choosing a handheld VHF radio. You want a radio that can last through your entire trip without needing constant recharging. Many handheld radios come with rechargeable batteries, but some also offer the option to use disposable batteries as a backup. This can be helpful in situations where you don’t have access to electricity.
Power Output
Digital Selective Calling (DSC)
GPS Integration
Weather Alerts
User-Friendly Interface/Ease of Use
Antenna
The quality, length, and height of the antenna significantly impact the performance of your VHF radio. Fixed-mount radios usually require an external antenna, and the higher you mount it, the greater your communication range. Make sure to invest in a good-quality antenna if you’re opting for a fixed-mount radio. For a handheld VHF radio, an attachable antenna comes with the device, but you can still check reviews for their performance.
Regulations and Licensing
In many countries, using a VHF radio requires a license, especially for marine communication. This is to ensure that radio frequencies are used correctly and not misused.
Make sure to check your local regulations before purchasing and using a VHF radio. Some marine VHF radios also come pre-programmed with specific channels for maritime communication, and others may require you to program the marine, emergency, or weather channels yourself.
Price and Budget
Finally, you’ll need to consider your budget when buying a VHF radio. Prices will vary greatly depending upon the amount and type of features, the radio brand, and type of radio.
A handheld VHF radio is generally more affordable. Fixed-mount radios tend to be more expensive, with higher price points for units with advanced features like Digital Selective Calling (DSC) and GPS integration.
Keep in mind that investing in a good-quality fixed-mount or handheld VHF radio can enhance your communication and maybe one day save a life! So, it may well be worth spending a little extra for reliable performance and essential features.
All Things Considered
When choosing a VHF radio, consider how and where you’ll be using it. Think about the size of your boat or vehicle, the range you need, and the features that are most important for your safety and convenience.
Whether you choose a handheld or fixed-mount radio, make sure it meets the requirements for waterproofing, battery life, and power output. Keep safety features like DSC and GPS in mind, and don’t forget to check local regulations about licensing.
With the right VHF radio, you’ll have a reliable communication tool that can make your time on the water safer and more enjoyable.
