Enter the antenna height into the calculator to determine the line of sight distance and service range of the antenna.
Line of Sight Formula
The following equations can be used to calculate the line of sight and service range distance of an antenna.
LOS = 3.57 * SQRT ( h)
SR = 4.12 * SQRT (h)
- Where LOS is the line of sight distance (km)
- SR is the service range (km)
- h is the antenna height (m)
A line of sight is the distance to the horizon an object can “see” from it’s position. The taller the antenna the taller the line of sight.
A service rand is a similar distance to line of sight, but takes into account the extra bit of range acquired from bouncing radio waves.
