Why you should get Dual-Band Two-Way Radio

Whether you’ll be adventuring with a small group into the woods or embarking on a solo journey, it’s crucial to keep track of your location for safety and preparedness. Proper navigation can prevent potentially dangerous situations, ensuring you remain on course and can be located if necessary.

It’s essential to inform someone of your destination, the route you plan to take, and the number of days you intend to be on the trails. This information can be vital in case of an emergency, providing rescuers with a starting point for their search efforts. Additionally, having a detailed map, compass, and GPS device can enhance your ability to navigate the terrain confidently.

Using a two-way radio, which often requires extra training and, in some cases, additional governmental certifications, ensures stable, constant communication with your team or the nearest communication station.

Unlike cell phones, which depend on network coverage and battery life, two-way radios provide a reliable means of communication, especially in remote areas where cell service is nonexistent. This allows for immediate contact in case of an emergency, coordination with other group members, and receiving updates on weather conditions or other critical information.

Packing a two-way radio among your essentials eliminates the need to worry about maintaining a cell phone signal or carrying a power brick for recharging, thus enhancing your overall safety and communication capabilities during your adventure.

What is dual-band two-way radio used for?

The reality is that in life-threatening situations, particularly during disaster events, few technologies match the reliability and resilience of a dual-band two-way radio. During catastrophic natural disasters like hurricanes or earthquakes, where critical infrastructure is heavily compromised and power outages are inevitable, communication through radio signals becomes the primary means of coordinating rescue efforts and updating nearby communities.

In such scenarios, having a dual-band two-way radio can be the difference between life and death. Even if you don’t pack one for your camping trip, simply having one at home makes you more prepared than most in the event of another disaster. This preparedness can provide peace of mind, knowing that you have a reliable way to communicate when other systems fail.

Unlike cell phones, which depend on network coverage that can be disrupted, dual-band radios use radio signals that can cut through the chaos, ensuring you stay connected when it matters most.

Ideal Use of Two-Way Radios in Outdoor Scenarios

In an outdoor scenario, especially on a mission that will take more than a day to complete, carrying a two-way radio is ideal. If you are venturing into areas known for poor cell phone signals, having a radio as a backup ensures you can maintain emergency communication with the nearest station. Before heading out, your group should coordinate which channels to use to stay in contact, establishing clear signals for efficient communication and emergency situations. This preparation allows for continuous updates and ensures that if someone takes longer than expected to complete their tasks, they can still communicate their status and avoid causing unnecessary worry. By staying in touch through reliable radio signals, your group can navigate the challenges of the wilderness more safely and efficiently.

How does a dual-band two-way radio work?

A radio can be classified as dual-band when it allows operation on two separate frequency bands. In this particular case, it would allow for ultra-high frequency (UHF) and very high frequency (VHF).

The UHF band typically ranges from 400 to 470 MHz, while the VHF band ranges between 136 and 174 MHz. Of course, these numbers are only references, and what’s most important is that there are some two-way radio frequencies allocated as license-free for personal use, such as the Family Radio Service (FRS) and General Mobile Radio Service (GMRS) in the U.S. Otherwise, you would need to go through certification processes with your respective authority if you’re looking to dive into the amateur radio hobby.

For survivalists and people who want to have a survival kit prepared in the back of their car, it’s ideal to have both options available in a single piece of equipment. Ultra-high frequency can easily penetrate through buildings and densely wooded areas, at the cost of having a lower distance. On the other hand, very high frequency is normally reserved for outdoor situations and rural areas since it can cover more distance. Having the ability to switch frequencies accordingly is crucial to maintain contact with your group or your nearest safe point.

How to choose a dual-band two-way radio?

Before settling on a specific two-way radio model, it’s important to consider how many headsets are included, especially if you plan to use them in a group. Some manufacturers offer packs of four or more headsets, which is ideal for larger groups. If you’re only planning to use a pair for a reduced range, then a smaller set may suffice.

What to look for in a two way radio dual band?

Most dual-band two-way radios have the option to program channels according to the user’s needs and incorporate some common features across all models, regardless of the manufacturer. For example, license-free two-way radios in Europe can transmit on PMR446 frequencies, while in the U.S., FRS and GMRS frequencies are commonly used. Another factor to consider before purchasing is the number of channels each handset can communicate with, usually either 8 or 16. Survivalists will benefit from a radio with a removable antenna, which allows for switching and upgrading to achieve better performance in more isolated areas. If you’re interested in using your radio in extreme situations, such as mountain climbing, a Voice Activated Transmit (VOX) feature will keep the radio’s microphone on at all times and automatically transmit your voice when you start speaking. These models should also come with a throat mic or a socket for a headset to complement the VOX system.

Although amateur dual-band two-way radios, also known as “ham” radios among enthusiasts, might require a license to operate for more complex tasks depending on where you live, a good alternative could be using regular walkie-talkies for simpler communication needs.

The biggest disadvantage of these simpler devices is that you cannot communicate outside of your designated channels if something goes wrong and you need help from any authority. Finally, regardless of the decision you make, it is crucial to purchase a device that is waterproof or uses protective gear to ensure that your radio can withstand harsh weather conditions.
