CB Radio

Citizens' Band Radio (also known as CB radio) is, in many countries, a system of short-distance radio communications between individuals on a selection of 40 channels within the 27-MHz (11 m) band. It is mainly used by emergency services to dispatch personnel to areas that require attention whether medical or lawful. It is also used by The Military to coordinate troop deployment and movement as well as aiding in providing support. Both "ham" and handheld radios are seen throughout The Walking Dead series being used by different personnel.

Usage
The purpose was to remain in contact with other personnel or survivors in the TV Series. People would keep them around in case anyone was broadcasting as well as to listen for instructions from officials about the outbreak. After the apocalypse, people still continued to use radios in the rare event they do reach out to someone.
