Whether you’re navigating the outback, planning an off-road adventure, or just want a reliable communication tool for camping or caravanning, UHF CB radios have become a must-have for many Australians.
These radios offer the perfect solution for short-range, fee-free communication, and it’s never been easier to get connected – so we’ve partnered with Australia’s leading UHF CB radio manufacturer, Oricom, to give you a rundown of everything you need to know about using UHF CB radios in Australia.
We’re fans of Oricom’s range of UHF CB radios – firstly because we use them and we’ve always found them suitable for whatever we throw at them – but secondly because they’re a 100% Australian-owned company – which means you’re getting good old-fashioned Aussie quality and customer service values when you deal with them.
What is a UHF CB Radio?
UHF CB (Ultra High-Frequency Citizens Band) radios operate on a specific frequency range (476.4250 to 477.4125MHz) and provide short-distance two-way communication without any ongoing costs.
Unlike mobile phones, UHF CB radios don’t rely on cell towers, making them ideal for out-of-service locations or remote areas where connectivity is key. They operate over 80 channels, each dedicated to a different type of communication, from highway talk to emergency services.
The Benefits of UHF CB Communication
The appeal of UHF CB radios goes beyond simply staying in touch. They offer a direct, clear connection between users in situations where mobile coverage might be patchy or non-existent.
For off-roaders, campers, fishermen, or others who find themselves in out-of-the-way places, CB radios serve as an essential link, whether you’re checking in with friends or coordinating tricky 4WD trails.
Best of all, once you’ve got the radio, there are no subscription fees—just pure, uninterrupted communication.
Aussie UHF CB Radio Channels
Here’s a handy chart that shows you the channels that different groups of people typically use:
Choosing the Right UHF CB Radio
When you’re in the market for a UHF CB radio, it’s easy to feel overwhelmed by options.
The key is finding one that matches your specific needs. Oricom has built a reputation for delivering quality without breaking the bank, and their range of in-vehicle and hand-held radios is no exception.
For those with limited dashboard space, it’s a good idea to consider a compact unit like the Oricom DTX4200X or UHF390, where the controls are built right into the microphone itself. This space-saving, easy-to-install design is perfect for drivers who need clear communication but don’t want to clutter up their vehicle’s interior. The controller speaker mic takes care of both volume and sound quality, giving you seamless, reliable audio.
One of the biggest reasons we love the Oricom range is their unique, Dual Receive function. Dual Receive lets you listen to two channels simultaneously – without the need for two devices. Being able to monitor two different channels means you can keep an ear on, say, the Highway Channel, while being able to talk to friends on a less busy frequency. It’s a handy function that we use a lot more than we thought we would!
Why Go Hand-held?
If portability is what you need, hand-held UHF CB radios are a great option. You can pair them with an in-vehicle setup or use them standalone while exploring on foot or setting up camp.
The Oricom DTX600, for instance, is a robust 5-watt hand-held option that delivers exceptional performance even in harsh conditions. Its switchable RF power and fast-charging capabilities make it ideal for those on the go—perfect for off-road navigation, managing tricky terrain, or even backing up your vehicle with a trailer in tow.
Antennas: The Unsung Hero
No UHF CB radio setup is complete without the right antenna – and your choice will depend on the environment you’re operating in. The gain of an antenna determines the strength and direction of the radio signal, which can make all the difference when navigating various terrains.
- 3dBi Gain Antennas have a wide radiation pattern, making them ideal for undulating terrain. These antennas provide good coverage in hilly areas, offering a broader but shorter communication range.
- 6.5dBi Gain Antennas are popular for their all-round performance on flatter or slightly uneven terrain. With a narrower but longer radiation pattern, these antennas excel in delivering communication over longer distances when obstacles are minimal.
UHF CB radios operate using line-of-sight technology, meaning that reception is strongest when there are no physical barriers, such as hills, between you and the other radio user. As antenna gain increases, the radiation pattern flattens, meaning higher gain antennas, like the 6.5dBi, perform best in flatter environments.
Understanding how field strength patterns differ between antennas of varying gain can help you select the best setup for your needs. While signals can sometimes travel slightly beyond the direct line of sight, they are still limited by the horizon, so it’s crucial to match your antenna to the terrain you’ll be navigating.
UHF Radios and CB Radio Etiquette
Like all communication tools, there’s an unwritten code of conduct when using a UHF CB radio. Here are some key points to keep in mind:
- Emergency Channels (5 and 35): These are strictly reserved for emergency use only. Emergency services monitor these channels, so avoid unless you’re in a real emergency.
- Main Channels (like 40 for truckers): Once you’ve made contact, it’s courteous to shift your conversation to a different channel to keep the main ones clear.
- Public Communication: Remember, anyone within range can hear your conversation, so keep it clean and be mindful of others.
Is a UHF CB Radio Right for You?
If you regularly find yourself out of mobile range or simply want a more reliable way to stay connected, a UHF CB radio is a fantastic investment. We’re slightly biased because we use them – but Oricom’s range of in-vehicle and hand-held radios offer top-tier performance and durability, with easy-to-use controls and features that fit both seasoned adventurers and casual users alike.
From caravanners to weekend warriors, anyone who values clear, consistent communication without the hassle of phone signal dependency will find UHF CB radios indispensable. Combine that with the right antenna, and you’ve got yourself a reliable communication system no matter where the Aussie terrain takes you.
In short, UHF CB radios are as essential as a spare tyre or a jerry can of fuel when heading off-grid. With Oricom’s stellar reputation and top-notch products, you’ll have peace of mind knowing that you’re never truly out of touch, even when you’re miles from the nearest service station.
