Over-the-air broadcast signals are acquired at the head using which antennas?

• A. Yagi and log periodic antennas
• B. Parabolic and horn antennas
• C. Dipole and loop antennas
• D. Yagi and patch antennas

Answer: (A)

The signals from local broadcasts are best captured with antennas that provide both good gain and broad coverage across the VHF/UHF spectrum. A Yagi antenna is a classic directional design that delivers high gain on specific bands, making it effective for pulling in distant broadcast channels. A log-periodic antenna, on the other hand, is broadband and maintains relatively uniform performance across a wide frequency range, which is ideal when you need to receive many channels across the broadcast spectrum. At the headend, using these two types together gives you flexible, efficient reception of over-the-air signals. Parabolic and horn antennas are more typical for microwave or satellite links; dipole and loop antennas tend to be simpler and often narrower in band, and patch antennas aren’t suited to the broad, variable VHF/UHF reception needed here.
