What is a CB Radio?
Citizens’ band (CB) radio is a communication device that allows people to talk to each other using a radio frequency. The CB radio user has 40 channels to choose from and uses an 11 meter band or 27 MHz. CB radio was originally intended for use by government divisions such as the military, and in the 1960s, it was mainly used by taxi firms and tradesmen.

This licence cost a mere £10 per year, and you can contact anyone, anywhere in the world. With new technology such as the Internet, the CB radio seems to be dying out and breakers are hanging their microphones up for a keyboard and mouse. Yes both mediums have similar qualities, but what an achievement when you make a contact using a simple set up, such as a small 40 channel CB radio producing 4 watts of power, a small magmount (1-2ft magnetic based antenna) and as little power as a 3 amp power pa
