The purpose of a Wi-Fi antenna is to gather in the signals being transmitted so that a device can access a local network or Internet. Turn an old satellite dish, for example, a Direct TV satellite dish, into a powerful and efficient Wi-Fi antenna.
In electromagnetics, an antenna's power gain or simply gain is a key performance number which combines the antenna's directivity and electrical efficiency. As a transmitting antenna, the gain describes how well the antenna converts input power into radio waves headed in a specified direction. As a receiving antenna, the gain describes how well the antenna converts radio waves arriving from a specified direction into electrical power.
