Webwhere r is the actual earth radius and R e is the effective earth radius. Commonly, the effective earth radius factor, k, is chosen as 4/3.However, at long ranges and with shallow angles, k can deviate greatly from the 4/3. (With no atmospheric refraction, k = 1. An infinite value for k represents a flat Earth). ). The effearthradius function provides two methods … Earth bulge. In telecommunications, Earth bulge refers to the effect of earth's curvature on radio propagation. It is a consequence of a circular segment of earth profile that blocks off long-distance communications. Since the vacuum line of sight passes at varying heights over the Earth, the propagating radio … See more 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 … See more 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 … See more 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 See more • • Article on the importance of Line Of Sight for UHF reception • Attenuation Levels Through Roofs See more Although the frequencies used by mobile phones (cell phones) are in the line-of-sight range, they still function in cities. This is made possible by a combination of the following effects: See more • Anomalous propagation • Dipole field strength in free space • Knife-edge effect • Multilateration • Non-line-of-sight propagation See more

Web20. Many sources state that the Earth's gravity is stronger at the poles than the equator for two reasons: The centrifugal "force" cancels out the gravitational force minimally, more so at the equator than at the poles. The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field. the pirates bay moviesthe pirates bay freeWebIn this way the combination of gravity and inertia create two bulges of water.
