## Radio Distance Formula

The following formula is used to calculate the Radio Distance.

**RD = 3.569*SQRT(H)**

- Where RD is the Radio Distance (km)
- H is the height of the radio tower (m)

## How to Calculate Radio Distance?

The following example problems outline how to calculate Radio Distance.

Example Problem #1:

- First, determine the height of the radio tower (m).
- The height of the radio tower (m) is given as: 150.

- Finally, calculate the Radio Distance using the equation above:

RD = 3.569*SQRT(H)

The values given above are inserted into the equation below and the solution is calculated:

RD = 3.569*SQRT(150) = 43.71 (km)

Example Problem #2:** **

For this problem, the variables needed are provided below:

height of the radio tower (m) = 75

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

RD = 3.569*SQRT(H)** = ?**
