In the context of a TV distribution system, which carrier range is used for the downlink in the cable antenna relay service?

• A. 12.7 to 13.2 GHz
• B. 6.0 to 6.5 GHz
• C. 2.0 to 2.5 GHz
• D. 60 to 70 GHz

Answer: (A)

In a cable antenna relay system, the downlink path from the relay station to the subscriber’s antenna uses a high-frequency microwave band. The 12.7 to 13.2 GHz range is the designated downlink for this service, which sits in the Ku-band and is chosen to provide strong, multicast-friendly reception with focused beams. The return path from subscribers back to the headend typically uses the lower 6.0 to 6.5 GHz band, separating the directions to minimize interference. The other frequency options listed aren’t used for this downlink in standard cable antenna relay setups.
