Why are repeaters important for emergency communications?

• 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 emergency radio coverage by receiving a signal, boosting its power, and re-transmitting it over a wider area. This lets messages travel farther and reach responders who would be out of direct range or blocked by terrain, buildings, or distance, which is crucial during large incidents or across difficult terrain. The other ideas don’t fit the main role: storing calls isn’t what a repeater does, converting analog to digital is a different process, and providing backup power is a separate function. The primary purpose is to amplify and relay the signal to keep communications reliable where it’s needed most.
