CB radio is the abbreviation of the term citizens’ band radio. This type of communication is considered one of many two-way radio devices, but is completely different from ham radio. Using CB radio does not usually require a user to have a license, and there are no regulations as to the purpose of use – it can be used for personal or business purposes. In the United States, use of the CB radio came about around 1945, when the FCC allowed bands to be used for personal communication.
If you are planning on installing a CB radio in your vehicle, be sure that you are in compliance with regulations for these communication devices. There are rules and regulations governing the type of transmitter you are allowed to have for a personal vehicle – no high power transmitters – and you’ll have to be careful how tall your antenna is as well.
Today, CB radios have cropped up in various places in pop culture, and most notably in horror films. However, it is important to note that because of smart phones and the internet, people who make use of CB radios are more likely to be truckers communicating about traffic accidents, speed traps, and other important traveling information. It is up to the user to beware, because not everyone using a CB radio has the best of intentions, but if you know which frequencies are most used for informational purposes, you’ll be able to stay away from the more “shady” folks on the CB radio frequencies.
