Main mechanism: an approximately parabolic reflecting surface redirects incoming plane radio waves toward a receiver near its focus; drive bearings permit pointing.
Genuine scientific principles: geometrical focusing, diffraction-limited angular scale, collecting area and aperture gain. Engineering-inspired reconstruction: support ribs, bolted panels, bearings, feed enclosure, cabling and access equipment. Simplified educational representation: rigid surface, static focus and idealized efficiency. Speculative: exact actuator, encoder, service and receiver packaging.
Textbook: λ=c/f with c=299,792,458 m/s. Illustrative: D=26 m, f/D=0.40, θ≈1.22λ/D in radians, Aₑ=ηπD²/4, G=η(πD/λ)². Gain in dBi is 10 log₁₀(G). The independent form G=4πAₑ/λ² must agree numerically.
The light rays and any motion are teaching animations, not validated electromagnetic or structural simulations. The concept is not a measured installation. All dimension-like coordinates are illustrative scale.
