RF Line-of-Sight provides radio path information for mapping long distance SCADA radio communications by using antenna height and topography.
In obtaining the radar horizon equations, it is common practice to assume a value for the Earth's radius that is 4/3 times the actual radius. This is done to account for the effect of the atmosphere on radar propagation. For a true line of sight, such as used for optical search and ...
Creepage is the shortest distance between conductor traces on a PCB along the surface of the insulation material while clearance is defined as the minimum distance through the air (line of sight) between two conductor traces. Clearance and creepage distances between two PCB conductors. ...
