Best UHF Radios for Tow Vehicles: What to Buy and Why It Matters

If you're towing a caravan, a UHF radio isn't optional — it's essential. It keeps you connected on the road, lets you communicate with other travellers, and gives you access to road and weather updates in areas where mobile coverage drops out.

But with prices ranging from $150 to $600+, choosing the right one can be confusing. Here's what you need to know.

Why You Need a UHF Radio When Towing

• Truck communication — Channel 40 is the road channel. Truckies use it to warn about hazards, overtaking, and road conditions. When you're towing a 2.5-tonne caravan on a single-lane highway, knowing a road train is coming the other way is invaluable.
• Convoy travel — If you're travelling with mates or in a caravan club, UHF is how you stay in contact between vehicles.
• Emergency use — Channel 5 is the emergency channel. In remote areas with no phone signal, it could be your only way to call for help.
• Campground and caravan park info — Many parks and free camps have a nominated channel for local chatter.
• No ongoing costs — Unlike a satellite phone or mobile plan, UHF has no subscription fees. Buy it once, use it forever.

The Top UHF Radios for Tow Vehicles

GME XRS-330C — The Popular Choice

The GME XRS-330C comes up again and again in recommendations, and for good reason.

Why people love it: Excellent audio clarity, compact head unit that's easy to mount in modern dashboards, strong signal quality, and GME's reputation for reliability. The OLED display is easy to read at a glance while driving.

The downside: It's at the higher end of the price range. If you're on a budget, there are cheaper options that still do the job.

GME XRS-370C — The Step Up

Best for: Travellers who want Bluetooth phone integration and GPS location sharing. The Bluetooth feature means you can take phone calls through the UHF handpiece when your phone is connected — handy when the phone is mounted out of reach.

GME TX3350 — The Budget GME

Best for: People who want GME quality without the premium price. It lacks the OLED display and some of the XRS features, but the core radio performance is solid.

Uniden UH9080 — Strong Alternative

Best for: A mid-range option with good features. Uniden is a well-known brand and widely available. Good audio quality and easy to use.

Oricom UHF380 — Budget Friendly

Best for: First-time buyers who want a reliable radio without spending too much. Oricom is stocked at most auto and caravan accessory stores.

Quick Comparison

In-Dash vs Handheld: Which Do You Need?

In-dash (fixed mount) is what you want for a tow vehicle. These are permanently wired into your vehicle with an external antenna mounted on the roof or bull bar. They give you:

• Maximum 5-watt power (the legal limit)
• Better antenna placement for stronger signal
• Clearer audio through a proper speaker
• Hands-free operation with a mounted handpiece

Handheld UHF radios (the walkie-talkie style) are useful as a second radio — for example, giving one to your partner to guide you when reversing into a caravan site. But they're limited to about 2 watts on battery, and the built-in antenna is much weaker than a roof-mounted one. Don't rely on a handheld as your primary radio.

Many caravanners end up with both: a fixed mount in the tow vehicle and a cheap handheld pair for around camp.

The Antenna Matters More Than You Think

You can buy the best radio on the market, but if your antenna is poor, your range will suffer. A few things to know:

• Longer antenna = better range (generally). A 6.6dBi antenna gives more range than a 3dBi stubby.
• Roof-mounted is best. The higher the antenna, the better the signal. Bull bar mounts work but aren't as good as roof-mounted.
• Ground plane matters. The antenna needs a metal surface underneath it to work properly. Fibreglass roof? You'll need a ground plane kit.
• Match your antenna to your radio brand if possible, or buy a quality third-party antenna (GME, RFI, and Uniden all make good ones).
• Budget $80–$200 for a good antenna on top of the radio cost.

Installation: DIY or Professional?

Professional installation is recommended unless you're confident with automotive wiring. A typical install costs $100–$200 on top of the radio and antenna price. The installer will:

• Wire the radio to a switched power source
• Mount the head unit in a clean, accessible position
• Run the antenna cable with proper routing (away from other wiring to avoid interference)
• Mount the antenna and tune it for optimal SWR (standing wave ratio)

DIY is possible if you're handy. Most radios come with a wiring harness and instructions. The antenna cable routing is the fiddly part — you'll need to run it from the roof or bull bar through the firewall and into the cabin.

Key UHF Channels to Know

Tip: When towing on highways, keep your radio on Channel 40. You'll hear truckies calling out hazards, slow vehicles, and overtaking warnings. It's the single most useful thing a UHF radio does for caravanners.

Is the GME XRS-330C Worth the Money?

In short — yes, if your budget allows it. The audio quality, build quality, and compact design are genuinely a step above the cheaper options. GME is Australian-owned and manufactured, and their after-sales support is excellent.

But if $500 is a stretch, the GME TX3350 or Uniden UH9080 will still do everything you need. The core function — talking and listening on UHF — works the same across all of them. You're paying extra for better displays, audio processing, and features like Bluetooth.

Don't skip the radio to save money. A $200 radio with a good antenna is infinitely better than no radio at all.
