A directional antenna is a type of antenna designed to focus its signal in a specific direction, rather than radiating it equally in all directions. This focused design allows for improved signal strength and range, making it ideal for applications like Wi-Fi networks, telecommunications, and broadcasting. These antennas can be used to enhance communication between two points, such as connecting a router to a distant receiver. By concentrating the signal, directional antennas reduce interference from other sources and improve overall performance, making them a popular choice for both personal and professional use.
