Stay Cables

Cortland’s experience with high performance fibers has provided innovative solutions for critical structural components in industry, yachting and heavy duty applications. Super strong, all-weather resistant, not to mention aesthetically pleasing elements combine for maximum reliability.

Antenna Stay Cables

Cortland manufactures non-metallic, non-conducting aramid fiber tower guy cables equivalent in strength to extra high strength (EHS) steel cables traditionally used to support antenna towers. Our synthetic guy elements are about one-fourth the weight of a steel cable, and allow for a larger broadcast pattern as the synthetic cables are invisible to RF transmissions.  A high density polyethylene extruded cover protects the fiber cable from ultraviolet exposure, contamination and abrasion, and keeps the core of the cable dry to preserve its high dielectric properties and facilitates the shedding of rain, snow and ice. Aramid guy cables are lighter than steel, easier and safer to install and will not corrode.


Cortland manufactures high strength, low stretch, lightweight aramid fiber yacht backstays. The aramid fiber core is protected by a tough aesthetic which is not only visually appealing, but also keeps the core of the cable dry to preserve its high dielectric properties and protect the cable from environmental elements such as rain, snow, and ice. Some of the largest private sailing yachts in the world boast Cortland backstays, known for their high strength, low stretch, and lightweight properties.
