The line of sight (LOS) distance is calculated using the formula LOS = 3.57 × SQRT(h), where h is the height of the observation point in meters.
The Line of Sight Calculator is a useful tool for estimating the maximum direct distance between two points, considering the Earth's curvature. This is especially important in radio communication, antenna setup, and determining unobstructed paths for signals or visual observation.

What is Line of Sight Calculator?
A Line of Sight Calculator is a tool used to determine the straight-line distance between two points, factoring in obstacles, altitude, and curvature of the Earth. It is essential in applications like radio communications, satellite positioning, and surveying, where unobstructed signal paths are critical.
This calculator is particularly helpful for tasks such as finding the line of sight between two antennas or calculating the distance to the horizon based on the height of a transmitter or receiver.
Advanced tools, like the line of sight calculator on Google Maps, provide visual mapping, making it easier to plan for radio or optical communication systems.
It can also compute distances in various scenarios, such as radar line of sight, visual line of sight, or VHF radio range. By inputting values like antenna height or altitude, users can quickly determine the effective line of sight and address factors like Earth’s curvature or terrain interference.
Final Words:
Ultimately, the Line of Sight Calculator is an invaluable resource for ensuring signal clarity and accuracy in communication systems. It simplifies complex calculations, making it indispensable for engineers, surveyors, and communication enthusiasts.
