Signal Path Loss - Through the aether...

• Atmospheric Attenuation

  • Rain/Snow
  • Trees (Spring/Summer vs. Fall/Winter)
  • Typical Solution: Just need to have lots of signal
    • Needed fade margin will increase with distance.

• Refraction

  • Thermal Ducting
  • Marine Layers
  • Typical Solution: Diversity Reception

• Fresnel Zone Attenuation...
