Targeting over horizon This can also be explained on a flat earth right It’s done because of land terrain and better accuracy over long distance. Not my field so if I’m wrong. 1 NettetMost radio communications do not have line-of-sight between antennas. However, the signal will generally be significantly stronger within line-of-sight. When you actually have the Earth itself between the transmitters, that will usually cause enough attenuation that the communication won't work, which is why this formula works for aircraft radio …
