How do repeaters handle frequency bands during operation?

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

Answer: (C)

Repeaters extend coverage by receiving a weak signal on a designated input frequency within a band and re-transmitting it on a separate output frequency in the same or a related band. This receive-and-transmit cycle effectively boosts the signal and relays it over greater distances, allowing communication beyond the radio’s direct range. The input and output frequencies are paired with a fixed offset so the system can operate without self-interference. They don’t store calls or convert analog to digital, and they aren’t a source of backup power.
