How Radio Signals Propagate Over Terrain - Visual Explanation #3415330 (License: Personal Use)

The image depicts a central radio tower atop a green hill, emitting concentric wavefronts that diffract around the hill’s curvature to reach two yellow figures holding radios on either slope. Arrows indicate signal direction, illustrating how non-line-of-sight propagation enables reception beyond physical obstructions. The diagram emphasizes real-world RF behavior in terrain-limited environments.

Used in educational content about wireless communication, RF engineering, or telecommunications courses; matches user intent seeking intuitive explanations of signal propagation, antenna placement, or coverage planning.
