If transmitting and receiving antenna heights are increased, the radio line-of-sight range generally?

  • AIncreases
  • BDecreases to zero
  • CRemains exactly unchanged
  • DBecomes independent of Earth curvature
Report an error
Correct Answer: A. Increases
Explanation: Increasing antenna heights extends the geometric/radio horizon and therefore generally increases line-of-sight range.
Reference: Standard antenna and wave propagation: space-wave propagation
