WebNov 15, 2024 · A Ground Wave or Surface Wave Propagation: The electromagnetic waves emitted from the transmitting antenna propagate along the surface of the earth are … Ground Wave Used for a low-frequency range transmission, mostly less than 1 MHz. This type of propagation employs the use of large antennas order of which is equivalent to the wavelength of the waves and uses the ground or Troposphere for its propagation. Signals over large distances are not sent using this … See more Electromagnetic Waves also called Electromagnetic Radiations are basically defined as superimposed oscillations of an Electric and a … See more Question: Find the transmitting range for an antenna of height 100 meters. Solution: We know, the range of transmission for an antenna is, Distance = (2RHt)-1/2 where R = 6400 km and Height = o.1 km Substitute in the above … See more

WebThe ground wave signal is more stable. Since it travels the shortest path between the transmitter and the receiver, it arrives first and its path delay is much easier to estimate. The sky wave is reflected from the ionosphere and produces results similar to HF reception. Short paths make it possible to track the ground wave continuously.
