Question 3

Compare how Low Frequency (LF), High Frequency (HF), and Microwave signals are used to establish communication links beyond the line of sight.

For each of the three systems, you must describe:

  • A typical carrier frequency (or wavelength range).
  • How the electromagnetic waves travel or propagate from the transmitter to a receiver that is beyond the horizon.
  • A common practical application of this type of communication.
