What term describes the way radio waves move from the source antenna to the receiving end?

• A. Wave Propagation
• B. Datalink
• C. Antenna Gain
• D. FCC

Answer: (A)

Wave propagation describes how radio waves move from the source antenna to the receiving end. It covers the path the energy takes through space and how distance, obstacles, and the environment affect signal strength and quality. In drone communications, this helps explain why a link is strong with clear line-of-sight but can drop when buildings or terrain get in the way, and how the chosen frequency influences range and penetration. The other terms refer to different aspects: the data link is the channel carrying control and telemetry data, antenna gain is about how a specific antenna concentrates power, and the FCC is the regulatory body governing radio use. So, wave propagation is the term that best fits.
