Line of sight angle

Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver. Electromagnetic transmission includes light emissions traveling in a straight line. The rays or waves may be diffracted, refracted, … Se mer Low-powered microwave transmitters can be foiled by tree branches, or even heavy rain or snow. The presence of objects not in the direct line-of-sight can cause diffraction effects that disrupt radio transmissions. For the … Se mer The radio horizon is the locus of points at which direct rays from an antenna are tangential to the surface of the Earth. If the Earth were a perfect sphere without an atmosphere, the Se mer • • Article on the importance of Line Of Sight for UHF reception • Attenuation Levels Through Roofs Se mer Although the frequencies used by mobile phones (cell phones) are in the line-of-sight range, they still function in cities.
