About the CB Radio Band

You may operate your CB radio within the territorial limits of the fifty United States, the District of Columbia, and the Caribbean and Pacific Insular areas ("U.S."). You may also operate your CB radio on or over any other area of the world, except within the territorial limits of areas where radio-communications are regulated by another agency of the U.S. or within the territorial limits of any foreign government. You may also be permitted to use your CB radio in Canada subject to the rules of Industry Canada. Travelers to the U.S. may operate a CB radio within the U.S. as long the unit is FCC certificated.

There are no height restrictions for CB radio antennas mounted on vehicles or for hand-held units. For structures, the highest point of your CB radio antenna must not be more than 20 feet above the highest point of the building or tree on which it is mounted, or 60 feet above the ground. There are lower height limits if your CB radio antenna structure is located within two miles of an airport.

Rules & Regulations

The FCC rules and regulations for CB radio are codified in Title 47 of the Code of Federal Regulations (CFR). They are initially published in the Federal Register. The FCC does not maintain a database of its rules nor does it print or stock copies of the rules and regulations. That task is performed by the Government Printing Office (GPO). After October 1 of each year, the GPO compiles all the changes, additions, and deletions to the FCC rules and publishes an updated CFR.
