UHF Radios

About this range

A UHF radio is the one accessory every touring 4x4 should carry. It works where your phone does not, whether you are calling a convoy on a dirt track or a road train on the Plenty Highway. We stock the GME range, from compact in-car units like the XRS-330C and TX3350 to 5 watt handhelds such as the TX6600S, plus antenna mounts and brackets. Buy online with Australia-wide shipping, or have your radio wired in and tuned at our Burwood workshop in Melbourne.

How to choose a UHF radio

A UHF CB radio keeps you in touch with your convoy, trucks and other road users where there's no phone signal. No licence application is needed, but there are rules on channels and power.

  1. In-car or handheld

    A fixed in-car radio runs at up to 5 watts through a roof or bar-mounted antenna. A handheld is handy outside the vehicle but has less range.

  2. The antenna matters

    Low gain (around 2.1 dBi) suits hilly country, mid gain (5.1 to 6.6 dBi) suits suburbs and general touring, and high gain (8.1 dBi) suits flat outback (GME).

  3. Know the emergency channels

    Channels 5 and 35 are the emergency channels, and no tones may be used on them. Channels 22 and 23 are for telemetry only.

  4. Repeaters

    Repeaters extend your range: their outputs are channels 1 to 8 and 41 to 48, and you transmit on 31 to 38 and 71 to 78.

Choosing the right UHF radio

Start with how you will use it. A fixed in-car unit running the full 5 watts, the legal maximum for UHF CB in Australia, paired with a properly mounted external antenna will always outperform a handheld for range. Compact units like the GME XRS-330C or TX3350 hide the main body under the dash, with everything controlled from the microphone, so they suit modern cabins with nowhere to mount a full-size radio.

Handhelds make sense as a second radio or for spotters, camp and walking away from the vehicle. The GME TX6600S gives you the full 5 watts in a portable body, while a 1 watt twin pack like the TX667TP is a cheap way to keep the passenger vehicle or the kids on channel.

Do not forget the install. Antenna position and cable routing make a real difference to range, and a fold-down mounting bracket protects the antenna in car parks and under low branches. We fit and test radios at the Burwood workshop, so the whole setup works before you leave.

Common questions

Do I need a licence for a UHF radio?

No application or fee. UHF CB radios are covered by the ACMA's CB class licence, so you just follow its rules.

What are the emergency channels?

Channels 5 and 35. In a real emergency you may use any channel to get help (ACMA).

How powerful can my radio be?

Up to 5 watts of transmitter power (CB Class Licence 2025).

Which antenna should I choose?

Match the gain to where you drive: about 2.1 dBi in hills, 5.1 to 6.6 dBi for suburbs and general country, and 8.1 dBi for flat open country (GME).

How do repeaters work?

A repeater listens on one channel and re-broadcasts on another from a high point, extending your range. Repeater outputs are channels 1 to 8 and 41 to 48; you transmit on the matching input, 31 to 38 or 71 to 78. Running your own repeater needs an apparatus licence (ACMA).
