What is the term for a two-way radio that is permanently mounted in a vehicle?

The correct term for a two-way radio that is permanently mounted in a vehicle is mobile radio. Mobile radios are designed to be used in vehicles and are typically hardwired into the vehicle’s electrical system, providing reliable communication while on the move. These devices often have more power than portable radios, allowing for clearer communication over longer distances, and they may have features that facilitate use in emergency situations.

Portable radios, in contrast, are handheld devices that can be used anywhere but are not fixed in any location. Base stations refer to fixed communication setups that serve as the primary point for transmission and reception for two-way communication, typically found in a building or command center. Repeaters are devices that receive a signal and then retransmit it, extending the range of communication but not used as standalone communication units like mobile radios.
