A radio antenna is a device that transmits or receives radio waves, converting electrical signals to electromagnetic radiation or vice versa.
Antennas vary from simple wire dipoles to elaborate dish arrays, depending on frequency and purpose.
The radio antenna on the roof improved reception significantly.
Also called simply an antenna or, in British English, an aerial.
