Greyline Performance specializes in high-resilience RF infrastructure and Tactical LVP (Low Visibility Profile) assets. Rooted in a 35-year partnership of industry veterans, we deliver "Mission-Critical" hardware optimized for 100% duty-cycle operations. We command the entire signal chain—from the feedline to the radiator and the physics in between.

• Tactical LVP Systems: Signature-managed HF antenna systems (VLF/160M to 6M/UHF) for operational security in urban or restricted areas.
• Redundant Wireless Networks: Engineering fail-safe connectivity and custom antenna solutions for high-stakes environments.
• Material Science: Precision-machined 6061-T6 and Military-Grade 7075-T6 Aluminum for optimized strength-to-weight and corrosion resistance.
• Zero-Radial VDA Physics: Proprietary vertical dipole designs requiring no buried ground radials, enabling rapid deployment on any terrain.

• Intel-Sector Pedigree: Engineering team with active clearances and design history for the Pentagon, NASA, and the Red Cross.
• The "PhD-to-Recruit" Pipeline: Complex RF engineering distilled into hardware that can be successfully deployed by an 18-year-old recruit.
• Battle-Proven Reliability: A decade of global stress-testing in the amateur radio market across every climate and extreme on Earth.
• 100% Made in the USA: Ensuring supply chain security and compliance for government acquisitions (FAR 52.204-24).
