What are some wire types for antenna?

• A. Coaxial Cable
• B. Ribbon Wire
• C. Fiber Optic Cable
• D. Dipoles; Whip; Yagi

Answer: (D)

Antennas are defined by their radiating elements, not by the cables or media that feed them. Dipoles, whips, and Yagi configurations are classic wire-based antennas used to radiate RF energy. A dipole uses two conductors of roughly half a wavelength each and resonates as a simple, balanced radiator. A whip is a vertical monopole, a single rod that radiates when fed above a ground plane. A Yagi is a directional antenna that uses multiple elements (a driven element, a reflector, and directors) to shape and direct the beam.

Coaxial cable, ribbon wire, and fiber optic cable serve as feedlines or transmission media rather than radiating elements themselves. Coax carries RF to an antenna, ribbon wire is just a conductor, and fiber optics carry light, not RF radiation. So the names that reflect actual antenna designs—dipoles, whips, and Yagis—best match the question.
