A CB kicker is a linear amplifier used with a citizen’s band radio designed to increase the transmitting power of the radio and extend its operating range. Because CB kickers cause signals to spill over onto nearby electronic devices and other bands, they are illegal under FCC regulations.
Various CB radio bands and channels operate under different wattages or power outputs that limit the range of where the signal may be heard. Frustrated operators frequently turn to amplifiers to increase the power output of the radio and extend the range of the radio’s signal. However, these amplifiers, or “kickers,” frequently cause spill over or interference with nearby televisions, telephones and radio bands used in aviation and emergency vehicles. For these reasons, the FCC prohibits modifying CB radios in any way or from using linear amplifiers.
