In a typical repeater setup, how are receive and transmit frequencies related?

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

Answer: (D)

In a repeater, the receive and transmit frequencies are offset from each other. The repeater listens on one frequency (the input) and re-broadcasts on a different frequency (the output). This separation avoids the station’s own transmission from overwhelming its receiver and allows simultaneous two-way communication. Because the signal is received on one frequency and then re-transmitted on another, the repeater effectively extends coverage by retransmitting the signal to areas beyond the user’s direct reach. Among the options, describing the function as extending coverage by retransmitting on a separate frequency best matches how the frequencies relate. The other choices describe unrelated functions.
