Downtilt Calculator
Downtilt Calculators assist in determining the optimal angle for an antenna’s tilt concerning the horizontal plane. This angle, measured in degrees, influences the coverage area and signal strength of the antenna.
Formula of Downtilt Calculator
The formula utilized by the Downtilt Calculator is:
Downtilt Angle (θ) = arctan((H2 – H1) / D)
Where:
- θ: Represents the downtilt angle in degrees.
- H1: Signifies the height of the antenna above the ground at the base of the tower (in meters or feet).
- H2: Denotes the height of the antenna above the ground at the top of the tower (in meters or feet).
- D: Indicates the horizontal distance between the antenna and the point of interest (in meters or feet).
This formula enables precise calculation of the downtilt angle required for optimal signal coverage based on the antenna’s height and distance.

Example of Downtilt Calculator
Consider a scenario where an antenna is installed on a tower. The base of the tower stands 10 meters above the ground, the top of the tower extends 30 meters, and the distance between the antenna and the point of interest is 50 meters.
Applying the formula: θ = arctan((30 – 10) / 50) = arctan(20 / 50) ≈ arctan(0.4) ≈ 21.8°
Therefore, the optimal downtilt angle for this scenario is approximately 21.8 degrees.
