A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure. They are used commonly for ship masts, radio masts, wind turbines ...
A sailboat's mast is supported by shrouds and stays - nautical equivalents of guy wires The Sendeturm Jauerling is a partially guyed 141 meter tower built in 1958, consisting of a 35-metre-high free-standing steel framework tower, which carries a 106 meter guyed steel tube mast on the top
A radio mast base showing how virtually all lateral support is provided by the guy-wires. The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guy-wires. [1] A mast
Determined insufficient sized bolts on the makeshift lifting lug extension failed. The falling debris severed one of the tower's guy wires which caused the tower to whip back and forth and collapse.

A gin pole in use loading logs A gin pole used to install a weather vane atop the 200-foot steeple of a church Roof trusses being assembled with gin poles. A gin pole is a mast supported by one or more guy-wires that uses a pulley or block and tackle mounted on its upper end to lift loads. The lower end is braced or set in a shallow hole and ...
The mast should also have a DC path to ground, so that static electric charges on the mast can drain off. [3] Also at the base is a grounding switch, which is used to connect the mast to the ground system during maintenance operations to ensure that there is no chance that high voltage will be present on the mast when personnel are working on it.
The umbrella wires may also serve structurally as guy lines to support the mast. There are several different methods of feeding power from the transmitter to the antenna: In base feed, the mast is supported on a thick ceramic insulator which keeps it insulated from the ground, and the feedline from the transmitter is attached to the base of the ...
