Radios are classified by which characteristics?

• A. Power source
• B. Location and size
• C. Antenna type
• D. Brand and model

Answer: (B)

Radios are categorized by where they’re used and how big they are, because deployment and handling on the scene depend on that. Handheld, portable radios are small and battery-powered for quick, close-range communications you can carry with you. Mobile radios are mounted in vehicles, larger and more powerful, giving you longer reach while you’re moving. Base stations stay in one place at a command post or dispatch center, offering the most power and capacity for extended operations. This way of classifying helps determine portability, power needs, mounting requirements, and antenna performance in real-world situations. Details like power source, antenna type, or brand/model are important specifics, but they don’t define how the radio is used across different incident scales the way location and size do.
