A CB radio, or citizen band radio, is a short-distance, two-way radio that operates on 40 channels within the 27 MHz (11 m) band. CB radios are used for a variety of purposes, including communication between truck drivers, off-road enthusiasts, and outdoor adventurers.
Portable CB radios are designed to be easily carried and used on the go. They are typically smaller and lighter than base station CB radios, and they often have built-in features such as weather channels, noise reduction, and hands-free operation. Portable CB radios are ideal for use in vehicles, on boats, or in remote locations where a fixed radio is not practical.
