The Legal Limits of CB Radio Power
The maximum legal CB power output in the U.S. is 4 watts for AM and 12 watts (peak envelope power) for SSB, as measured at the antenna connection on the back of the radio. These limits are in place to prevent interference with other communications and to ensure fair use of the CB band.
Why Are CB Linear Amplifiers Banned?
The FCC banned the sale of linear amplifiers capable of operation from 24 to 35 MHz in the 1970s to discourage their use on the CB band. This ban was implemented to:
Prevent interference with other radio services
Maintain the intended short-range nature of CB radio
Ensure fair access to the CB band for all users
Consequences of Using CB Linear Amplifiers
Using a CB linear amplifier can lead to several issues:
Interference with neighboring electronic devices, such as televisions
Potential health risks associated with high RF output
Legal consequences, including fines from the FCC
Alternatives to CB Linear Amplifiers
For those seeking longer-range communication, consider:
Obtaining a ham radio license, which allows for legal use of higher power
Investing in a high-quality CB radio, coaxial cable, and antenna system
