Loss of power over distance (assuming no fresnel effect and nothing in the way). This a very idealised calculation and in practice everything interferes with the signal but it will give you a reasonable approximation of the actual loss over distance. enter the system frequency in mhz and the distance in either kilometers (km) or miles below and then click the 'Calculate' button. 1 ghz = 1000 mhz e.g. 2400 = 2.4 ghz. |
