Line of sight distance between two antennas

Nettet6. apr. 2024 · In ground wave transmission we should have an antenna with size comparable to the wavelength. In sky wave propagation we use the ionosphere to reflect the radio waves. In the space wave for one antenna with height h, the distance to the horizon is given by $\sqrt{2Rh}$. For the two antennas range is given by the addition … Nettet31. okt. 2024 · In telecommunication, path loss refers to the attenuation of the power radiated by the transmitter with an increase in distance. When a signal travels from a transmitter to a receiver through free space (vacuum) without any obstacles between the two (i.e., clear line of sight), the reduction in signal strength is referred to as the free …
