Which connector is a 75 ohm coaxial cable connector suitable for RG-6 and RG-59 cables and used for terminating video systems?

• A. BNC connector
• B. F connector
• C. RCA connector
• D. SMA connector

Answer: (B)

When you're dealing with video signals on coax, keeping the signal’s impedance matched is crucial to prevent reflections and loss. For consumer video on RG-6 or RG-59, the standard 75-ohm connection is the F-type connector. It threads onto the coax and provides a reliable, weather-resistant, screw-on interface that matches the cable’s impedance, which helps maintain signal quality from source to display. That’s why this connector is the best fit: it is specifically designed for 75-ohm coax used in video systems and is widely used for cable TV, satellite feeds, and other home video wiring. Other connectors don’t align with the same combination of impedance, mechanical style, and typical use—BNC is more common in professional or 50-ohm setups, RCA is a general-purpose plug that doesn’t preserve coax impedance for RF transmission, and SMA is a small 50-ohm connector used in higher-frequency applications.
