WebAnswer (1 of 4): For starters we need to discuss the frequency you are using. Line of sight VHF and UHF are mostly only useful as ground-wave and typically a vertical antenna with a low angle of radiation is preferable as it adds more relative power by its radiation profile. In the VHF to HF wor... WebJul 19, 2024 · Additionally, a signal with a lower wavelength travels a greater distance. As a result, a signal for wave propagation in the sky can go further. Thus, the drawbacks of ground wave propagation are removed by sky wave propagation. Applications of Sky Wave Propagation. Some important applications of sky wave propagation are mentioned below.
