Principal mechanism: A parabolic conductive surface collects distant radio-wave energy and reflects it towards a focal feed. Elevation and azimuth drives point the dish at the sky.
Textbook equations: λ = c/f; θ ≈ 1.22λ/D (circular-aperture Rayleigh estimate); Aeff = ηπD²/4; G = 4πAeff/λ². Units: m, Hz, radians, m² and dimensionless linear gain; reported gain is 10log₁₀(G) dBi.
Independent cross-check: gain from collecting area is independently recomputed using G = η(πD/λ)²; the results must agree. η = 0.65 is an illustrative constant, not a facility specification.
Genuine principles: geometric paraboloid focusing, radio receiver signal chain, alt-azimuth pointing, structural stiffness, aperture diffraction.
Engineering-inspired reconstruction: faceted mirror, braced lattice, bearings, gearbox placement, quadrupod, receiver and maintenance decks. Dimensions are scaled for communication; no actual engineering specification is claimed.
Educational simplification: monochromatic on-axis plane waves, ideal circular aperture, fixed illustrative efficiency and no atmospheric, blockage, spillover, polarisation or surface-error model. Beamwidth is a Rayleigh angular criterion, not a measured FWHM.
Illustrative animation: movement, field wavefronts and receiver glow are explanatory artwork, not validated full-wave electromagnetic, structural or servo simulations.
Speculative details: enclosure layout, sensor arrangement, cryogenic modules and access mechanisms are fictional designs.
