Question B-007-004-010

Polarization change often takes place on radio waves that are propagated over long distances. Which of these does not cause polarization change?

Correct Answer

Parabolic interaction

Explanation

Faraday rotation (interaction with Earth's magnetic field in the ionosphere) is the primary cause of polarization change for HF skywave. Ground reflections can also affect it. Parabolic interaction is not a standard term for this.
