LEO User Terminal Radomes

LEO User Terminal Radomes

Hydrophobic radomes allow LEO internet to deliver its world-changing connectivity. SHEERGARD® multi-material laminates provide a best-in-class hydrophobic surface that repels water and protects signals.

SHEERGARD® optimizes static contact as well as dynamic and sliding contact angles to actively enhance water runoff and prevent accumulation. LEO User Terminal Radome laminates also have a fully UV-blocking layer, protecting sensitive electronics and ensuring they perform at their best.

Product Details

Conventional multimaterial laminates can provide standard hydrophobicity, but that does not serve high-frequency LEO User Terminal Radomes well. To preserve signal integrity, SHEERGARD® laminates combine a hydrophobic surface with fluoropolymer and engineered solutions that actually repel water. Static contact as well as dynamic and sliding contact angles are all optimized for water run off, and this is combined with an effective UV blocking layer. This prevents water, snow and ice from affecting the radome – even under extreme environmental conditions.

Rigorous testing standards

Saint-Gobain Composite Solutions rigorously tests all SHEERGARD® radome products via software-modeled analytics, lab-scale material characterization, and most importantly, directly relevant application testing. Every SHEERGARD® radome complies with strict MIL.STD.810 testing – the military-leading standard for all environmental conditions including temperature, humidity, salt, fungus, and many more. Software modeling such as Finite Element Analysis and Thermal Analysis can yield information on deflections, factors of safety, and thermal management requirements. Application tests such as physical hail storm testing, destructive fabric testing, and real-life application exposure reveal key learnings in creating a truly optimized product. Our testing begins during the co-development process to develop relevant tests and gather data that allows us to create market-ready solutions quickly.
