Calculate Line of Sight and Service Range

Formula

The formulas to calculate the Line of Sight (LOS) and Service Range (SR) are:

\[ \text{LOS} = 3.57 \cdot \sqrt{h} \]

\[ \text{SR} = 4.12 \cdot \sqrt{h} \]

What is Line of Sight?

A line of sight is defined as the distance on the horizon that an object of some height can "see" with a direct line. It is crucial for determining the effective range of communication systems, such as antennas.

Example Calculation

Let's assume the following value:

Using the formulas:

\[ \text{LOS} = 3.57 \cdot \sqrt{100} = 35.7 \, \text{km} \]

\[ \text{SR} = 4.12 \cdot \sqrt{100} = 41.2 \, \text{km} \]

The Line of Sight (LOS) is 35.7 km and the Service Range (SR) is 41.2 km.
