What is the term for a two-way radio that is fixed inside a vehicle?

• A. Portable radio
• B. Handheld radio
• C. Base radio
• D. Mobile radio

Answer: (D)

In radio terminology, a two-way radio fixed inside a vehicle is called a mobile radio. This type is designed to be installed in a vehicle and powered from the vehicle’s electrical system, often connected to a vehicle antenna and sometimes an external power supply, providing reliable operation while moving and when in different locations.

Portable or handheld radios are meant to be carried by a person and run on batteries, suitable for field use away from vehicles. Base radios are stationary, installed at a fixed location like a dispatch center or building, and wired to a power supply.

So the mobile radio fits the scenario of being mounted and used from within a vehicle, making it the best term for a radio fixed inside a vehicle.
