guyed

Guyed is an engineering term describing a structure that gains most of its lateral stability from tensioned cables known as guy wires. A guyed structure uses these wires to resist wind and other horizontal loads, allowing tall heights with relatively slender primary members. The term derives from the noun guy, a rope or wire used to steady a structure.

Common uses include communications towers, radio masts, weather stations, and some temporary shelters or tents. Guyed towers can reach great heights because the loads are shared with multiple cables anchored outward and downward.

Typical configuration involves a vertical mast or tower supported by sets of guy wires attached at various heights and radiating to anchors on the ground or to other fixed structures. Anchors are usually concrete foundations or earth anchors. Turnbuckles and fittings adjust tension; insulators may be used if the guy wires form part of an antenna system rather than purely mechanical support.

Advantages and considerations: The primary advantage is high structural height or reach with lower metal mass than a free-standing tower. Disadvantages include the need for a clear area around the installation for the guy wires, ongoing maintenance of tensioned cables and anchors, vulnerability to ice buildup, and safety hazards during construction and maintenance.
