Citizen’s Band (CB Radio)

CB Radios are regulated by the FCC under

47 CFR 95 Subpart D

The CB Radio Frequencies are between:

  • 26 to 28 MHz
  • In the HF band
  • Uses AM and SSB

The General Rules for CB Radio are:

The maximum legal CB power output level in the U.S. is four watts for AM and 12 watts for SSB

Citizens Band (CB) Radio Service is a private two-way voice communication service for use in personal and business activities of the general public.

CB Radio range is typically from one to five miles.

License documents are neither needed nor issued and there are no age or citizenship requirements. As long as you use only an unmodified FCC certificated CB unit, you are provided authority to operate a CB unit in places where the FCC regulates radio communications.

An FCC certificated unit has an identifying label placed on it by the manufacturer.

You must not modify your CB unit internally. Doing so cancels its certification and you forfeit your authorization to use it.

Travelers to the U.S. may operate a CB unit within the U.S. as long the unit is FCC certificated.

CB Radio Antennas

There are no height restrictions for antennas mounted on vehicles or for hand-held units. For structures, the highest point of your 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 antenna structure is located within two miles of an airport.

No Call Signs on CB Radio

You may use an on-the-air pseudonym (“handle”) of your choosing.
