Which single document underpins a fixed link design?

  • A.The manufacturer's data sheet for the radio equipment
  • B.The licence issued by the national regulatory authority
  • C.The maintenance schedule agreed with the site operator
  • D.The path profile with terrain, curvature and Fresnel zone drawn

Answer: D

The profile settles antenna heights, clearance, reflection points and hop feasibility before any equipment is chosen, and every later calculation refers back to it. Data sheets, licences and maintenance plans all follow from the design rather than driving it. Drawing the geometry first, and only then considering equipment and margins, is the order that avoids discovering an impossible path after the hardware has been bought.
