4x4 CB & UHF Radios

Conquering the great outdoors of Australia can be mesmerizing and challenging. However, you could put yourself at great risk if you’re lost or you wander away from your convoy. The best solution is constant communication using an ultra-high frequency citizen band radio or UHF CB radio.

The UHF CB radio is a two-way radio that utilizes the 476.4250 to 477.4125 megahertz or MHz, the radio spectrum intended for short-distance communications. It comprises 80 channels and is for public access although not all the channels can be used by anyone for any reason as there are certain penalties for channel misuse.

UHF Radio communication etiquette

UHF radio communication is guided by the following etiquette:

Emergency services monitor Channel 5 for calls for help and should strictly be used for emergencies along with Channel 35. Once you have established communication, both parties should continue into another channel to free up the channel. All communications on the channels are public so any person within your range or a repeater can hear you and join in. UHF radio communication is a vital link to the outside world especially when there are discrepancies or emergencies.
