Understanding UHF CB Radio Power Output
The power output of a UHF CB radio determines its range and suitability for different purposes. UHF CB radios are commonly used for communication in vehicles, boats, and outdoor activities such as camping and hiking.
5-watt UHF CB radios are the most powerful option, delivering the greatest range — up to 20 km (12 miles) in good conditions. Favoured by professional drivers, emergency services, and long-distance travellers.
1-watt UHF CB radios offer a shorter range for personal and short-range communication — up to 5 km (3 miles) in good conditions.
0.5-watt UHF CB radios are suited for short-range communication within a small group, with a range of up to 1 km (0.6 miles) in good conditions.
