[ Video ] Fresnel zone calculation tool

To establish good communication between the transmitter and receiver, it is not enough to just have a visible line of sight between the antennas. A certain space known as the Fresnel zone has to surround the line of sight path to allow all waves to reach the receiver.

Since most of the energy is contained in the first Fresnel zone, all that is needed for effective communication is to keep the first zone clear of obstructions.

Therefore, Circuit Design has created a tool that can calculate the first Fresnel zone, informing engineers the minimum height the antennas must be during their installation.
