What Is a Radio Antenna?
A radio antenna is a device that transmits and receives radio waves, functioning as a metallic conductor.
Its operation is based on emitting or capturing electromagnetic waves through a metallic conductor. The antenna’s length correlates with the wavelength of the radio waves, generally spanning from a few centimeters to several meters. Radio antennas are usable in any location where radio broadcasts can be received, though reception might degrade in areas challenged by radio wave propagation, such as mountainous terrains or subterranean locations.
During operation, radio waves from broadcasting stations reach the antenna and convert into electrical signals. These signals are transmitted to a radio, transforming into audible outputs like voices or music. Available in various designs, radio antennas provide differing directionality and gain and are straightforward to install.
