Gain What gain is How it is expressed How it is connected to an antenna
Gain (Horse Power + Drivetrain) An antenna's power gain or simply gain is a key performance figure 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. Due to reciprocity, the specified gain for any antenna applies identically whether it is used for transmitting or receiving.
