What is the primary purpose of using a repeater in EMS radio networks?

• A. To extend communication range by retransmitting at higher power
• B. To shorten signal distance
• C. To convert analog to digital
• D. To switch frequencies automatically

Answer: (A)

A repeater’s job is to extend communication reach by capturing a weak signal from a unit and re-transmitting it at higher power (often from a higher location). This boosts the signal so radios that are farther away or blocked by terrain can hear each other and dispatch. It’s not about shortening distance, converting analog to digital, or automatically switching frequencies—the primary purpose is to relay the signal to cover a larger area and improve reliability in EMS operations.
