Company Overview
About Greyline Performance
Greyline Performance designs and manufactures high-resilience HF antenna infrastructure for amateur radio operators, government agencies, defense contractors, and emergency management organizations. Our VDA (Vertical Dipole Antenna) systems require no buried radial field, deploy on any surface, and operate at 100% duty cycle across 1.8–54 MHz. Systems are in active service with US embassies, state emergency operations centers, and defense contractors. All products are manufactured in Sun Valley, Idaho from domestic materials.
Core Competencies
What We Deliver
Low Visibility HF Systems
Antenna systems presenting as standard commercial-grade flagpoles. Internal antenna function — no visible stubs, loading coils, or external evidence. 160M–6M from a single feedpoint. Appropriate for installations requiring a discrete RF profile.
Zero-Radial VDA Physics
Proprietary OCF Vertical Dipole Antenna design. Return current flows through the lower element rather than through a buried radial field. Deployable on rooftop, concrete, asphalt, or frozen soil. Performance independent of ground conductivity.
Mission-Grade Construction
Heavy-wall 6061-T6 aluminum alloy, 316 marine-grade stainless hardware throughout. ASCE 7-10 wind load engineered. 7-year structural guarantee. No traps, no coils, no failure points under sustained digital operation.
Rapid Deployment
No radial installation, no ground system preparation. Single ground sleeve. Operational in minutes on any surface. Compatible with ALE, STANAG 4538, MIL-STD-188-141B, and all digital HF modes.
