What describes a radio that an officer carries on their person?

A portable radio is designed to be used by individuals for communication while on the move, which is why it is the appropriate choice for describing the type of radio an officer carries on their person. These radios are typically lightweight, compact, and built to allow officers to remain connected while performing their duties away from their vehicles or stations, facilitating real-time communication in various situations.

In contrast, stationary radios and base radios are generally set up in fixed locations, such as police stations or dispatch centers, to manage communication across broader areas rather than for individual, personal use. Fixed radios, while similar to base radios, also refer to equipment that is mounted in one location, which does not support the dynamic nature of an officer's duties. Therefore, the distinction of portability is vital in identifying the type of radio that best describes an officer's personal communication device.
