List of masts - Wikipedia, the free encyclopedia (331 words) |
 | 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. |
| The Petronius Compliant Tower is an oil platform standing 2100 ft or 640 m (to the top of the spire) and is the tallest non-guyed structure in existence but is mostly underwater. |
