When you are looking to enter the world of citizen band radio, there are a lot of things to learn. Before you start learning the terminology associated with Cb and ham radio, it is a good idea to understand the basics behind the electronics. You can use an antenna to send out radio frequencies to truckers or amateurs. Become familiar with the following key terms before you start exploring the world of amateur and citizen band radio.
Bandwidth - A measurement of the width of the band of frequencies that is used in a radio transmission. This is measured by the difference between the highest and lowest frequencies in hertz.
Hertz - An alternating current frequency of one cycle per second.
Band Spread - A term that is used to describe how far apart stations are on nearby frequencies. A short distance between a nearby frequency will increase likelihood for interference.
Dummy Antenna - An accessory that gives you the opportunity to test your equipment without sending signals through the airwaves. This can also be referred to as dummy load.
Ham-Bands-Only Receiver - This is a receiver that is designed to only pick up stations used by amateurs. Cb or citizen band radio is also considered amateur. The bands will usually range from 80 to 10 meters on this type of receiver.

Citizens band radio, often called CB radio for short, is a term used to describe a system of short-distance radio communications between individuals over a total of 40 channels on the 27-MHz (11 m) band.
Used for both personal and business purposes, CB radios are typically found in trucks, and are utilized by truck drivers as they travel the roadways. It's a primary mode of communication between truckers and others who have access to CB radios. Several users share this two-way radio service, but only one station can transmit communications at one time. This requires one person to listen and wait for the channel to be freed up before speaking.
Citizens band radios contain many components to work, including an antenna, amplifier, speaker, and microphone. Some CB radios are fixed, as in the case of systems within trucks, while others are portable. From handheld CB frequency transceivers to short wave radio equipment and antennas, citizens band radio providers offer sales of these devices but also repair and parts replacement by qualified technicians.
CB radios experienced growing popularity in the 1970s, as more and more truckers in particular began using these two-way broadcast frequencies to communicate to each other about anything from speed traps to the nearest service station locations. Whether used for commercial or personal communication, CB radios can be found at hobby shops, electronics stores, and online.
Providers of citizens band radios usually also sell police scanners, amplifiers, mobile devices, and accessories. Buying directly from the manufacture can bring on some deep savings, while buying at a retailer may be just right for the amateur CB user looking to get into this hobby.
