Not to be confused with similar services in the United States and Europe. The term UHF CB may refer to the license-free FRS service and/or GMRS service (which allows use of repeaters) in the United States. Use of the Australian UHF CB frequencies outside Australia, New Zealand, Malaysia and Indonesia is not permitted and will very quickly get the attention of government authorities.
In the US, the FRS/GMRS band operates on the UHF band, but uses different frequencies. A "VHF CB" service is also available in the US - the license free MURS service.
