Antenna Downtilt Angle Calculator Usage Guide

Learn how to use the Antenna Downtilt Angle Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the distance from the antenna to the coverage area in meters.
  2. Enter the desired horizontal coverage radius in meters.
  3. Click the "Calculate" button to compute the downtilt angle.
  4. The result will be displayed in degrees.

Working Principle

The downtilt angle of an antenna is calculated using the formula θ = arctan((2 * R) / D), where R is the horizontal coverage radius and D is the distance from the antenna to the coverage area. This angle helps in optimizing the coverage area by ensuring that the signal is directed downwards at the correct angle.

Applications

This calculator is useful for network engineers and technicians who need to optimize antenna placement and configuration for wireless communication systems, including cellular networks, satellite communications, and Wi-Fi networks.
