Which function best defines what a repeater does in a radio network?

• A. To store emergency calls for later review
• B. To amplify the radio signal to extend coverage
• C. To convert analog signals to digital
• D. To provide a backup power source

Answer: (B)

A repeater’s job is to extend radio coverage by receiving a signal, boosting its strength, and retransmitting it on a different frequency. This relays communications through obstacles or over greater distances, often by located at a high site so radios in areas with poor line-of-sight can still talk to units farther away. It helps create a larger, more reliable coverage area without requiring everyone to be close to a transmitter. Storing emergency calls, converting analog to digital, or providing a backup power source are separate functions handled by other equipment or systems, not the core role of a repeater.
