High-performance materials for radomes and antennas

Ideal radome materials are both extremely pure and low dielectric, meaning they truly are transparent to electric signals. TenCate is the world's leading provider of high-purity, low dielectric structural radome materials. From environmentally demanding military applications to high-volume commercial aerospace satellite communications, TenCate's materials deliver.

We achieve superior quality through our precise manufacturing process. TenCate's radome materials are produced in facilities free of carbon fiber and conductive material contaminants, ensuring the lowest risk, highest performing electrically pure products for your radome.

Our radome materials are cyanate ester and epoxy-based prepregs, featuring the industry's lowest density, dielectric constant, dielectric loss tangent, moisture absorption, and coefficient of thermal expansion on the market.

No other provider offers the reliability, pedigree, and technical support for your mission critical radome program.
