A mast is a man-made support structure, commonly used on sailing ships as support for sails, or on land as radio masts and towers used to support telecommunication equipment such as radio antennas ("aerials" in the UK).
Most of the taller masts are located in the United States, where a prevalence of masts of around 2000 feet (609.6 m) in height is the result of special rules in that country limiting structures and objects taller than 2000 feet.
