Tactical LVP: The 20' Residential Stealth Workhorse
The definitive "Hidden in Plain Sight" solution for the modern radio operator.
The Greyline 20' DX System is the workhorse of our lineup, specifically engineered as a Permanent Property Asset for environments with strict 20-foot height limitations. This Tactical LVP (Low Visibility Profile) radiator delivers uncompromised 160-6M performance, utilizing our proprietary Vertical Dipole Antenna (VDA) physics to provide a low-noise, high-efficiency signal without the need for unsightly radial fields.
Engineered for Resilience Built from heavy-wall 6061-T6 Aircraft-Grade aluminum, the 20' DX is rated for extreme wind environments (up to 155 MPH). Whether you are chasing long-haul DX from a suburban lot or maintaining mission-critical EMCOMM readiness, this system provides the professional reliability of an embassy-grade installation in an elegant, HOA-approved profile.
