In the cable antenna relay service, the over-the-air signal is converted to a frequency in which band?

• A. 12.7 to 13.2 GHz band
• B. 6.0 to 6.5 GHz band
• C. 2.4 to 2.5 GHz band
• D. 60 to 70 GHz band

Answer: (A)

In cable antenna relay service, the over-the-air signal is moved onto a microwave relay link for transport to the cable system. That relay uses a high-frequency band in the Ku range, specifically 12.7 to 13.2 GHz. This band is chosen because it supports line-of-sight transmission with relatively small antennas and sufficient bandwidth to carry multiple TV programs to the headend. Once the signal reaches the headend, it’s converted back to the cable’s normal distribution frequencies for delivery to subscribers.
