Line of Sight Calculator

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)

FAQ

What is a line of sight?

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.

What is a service range?

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.
