Guy wire is used to stabilize and secure free-standing structures. It is commonly used by professional tower erecting companies to install towers in the antenna, communications and utility industries. 
The Guy Wire Name
Guy wire has many names. It is also known as guyed wire, guy cable, guy strand, and guy anchors. People also (mistakenly) call it guide wire. The name guy wire is derived from the term guy: defined as a rope, cord or cable used to steady, guide, or secure something.
Guy Wire Description
Guy wire is a tensioned cable that is both lightweight and strong. US Cargo Control extra high strength (EHS) guy wire meets ASTM A475, and is available in two types: 1×7 and 1×19, in several sizes.
