📏 Distance Attenuation Calculator
Calculate signal attenuation over distance for various wave types
📐 Attenuation Formulas
Free Space: L = 20 × log₁₀(4πd/λ)
Inverse Square: P₂ = P₁ × (d₁/d₂)²
dB Attenuation = 20 × log₁₀(d₂/d₁)
Atmospheric: L = L₀ + αd
L = path loss, d = distance, λ = wavelength, P = power, α = attenuation coefficient

💡 Tips & Information
- Free space path loss increases with frequency and distance
- Inverse square law applies to point sources
- Atmospheric conditions significantly affect radio waves
- Cable loss is linear with length
- Higher frequencies experience more attenuation
