What is a ground reflection range?

  • A.One where the antenna is mounted at ground level to avoid tower construction
  • B.One that measures the reflection coefficient of the ground beneath the path
  • C.One that uses the ground reflection deliberately to create a uniform field
  • D.One in which the ground is covered with absorber to remove the reflection

Answer: C

Rather than fighting the reflection, this design chooses the geometry so that the direct and reflected waves combine into a smooth taper across the test aperture, giving a controlled illumination. It suits lower frequencies where absorber and elevation are impractical. Absorber covering describes a different treatment, ground level mounting would not work, and measuring the ground is a separate exercise. Turning an unavoidable second path into part of the design is an unusually neat piece of engineering.
