Radio tower

Radio masts and towers are, typically, tall structures designed to support antennas (also known as aerials) for telecommunications and broadcasting, including television. They are among the tallest man-made structures. Similar structures include electricity pylons and towers for wind turbines. Masts are usually named after the broadcasting organisations that use them, or after a nearby city or town. ... In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. [Radio masts and towers. Wikipedia]
