WebExplanation: Radio horizon is the point to which a space wave can reach maximum and is greater than optical horizon. LOS is thedistance covered by a direct space wave from transmitting to receiving antenna. If distance between antennas is less than LOS then it is referred as Optical horizon and is approximated to LOS. WebTo use the calculator, simply type in your antenna height above ground in the appropriate window below and click the "Compute" button. You will see the actual line of sight distance to the horizon in the "Distance" section before the radio waves are attenuated by the curvature of the Earth. As an example using "Height in Feet" in the calculator ...

WebMay 7, 2024 · The usual "distance to horizon" calculation is for line of sight... so the correction is for that line and the horizon marking out a cone with apex at eye height above the ground. However, considering the distance in question is less than 3mi, that correction will be much smaller than the ones for refraction and attenuation in the air which are … WebThis is the radio horizon. The distance to the radio horizon also depends on height, as shown in Figures 1A and 1B.
