The Antenna connector provides which port?

• A. 50-ohm antenna port.
• B. 75-ohm port.
• C. 600-ohm line.
• D. Ground only.

Answer: (A)

The Antenna connector is designed to provide a 50-ohm antenna port. In RF systems, the feed point to the antenna is kept at a standard impedance (50 ohms) to maximize power transfer and minimize reflections back into the transmitter or receiver. That’s why the antenna interface is a 50-ohm port. The other options don’t fit typical RF practice: 75-ohm ports are used in some video and cable applications, 600-ohm lines are from older telephone-era architectures, and a ground-only connection would not carry the RF signal to the antenna.
