Tactical LVP: The 28' Elite HF Vertical & Permanent Property Asset
The uncompromised DX powerhouse for serious Amateur Radio operators and mission-critical Emergency Agencies.
The Greyline 28' DX Flagpole is our maximum-performance system, specifically engineered to provide world-class All-Band or Multi-Band efficiency (1.5-30 MHz) while maintaining a Tactical LVP (Low Visibility Profile). This is a Permanent Property Asset designed to be "hidden in plain sight"—offering the high-gain advantages of a commercial vertical radiator disguised as a functional, federally compliant flagpole.
Dual-Use Engineering: The Embassy Standard Originally refined for US Embassy disaster recovery and defense contractor interoperability, we have packaged this elite RF performance into an HOA-Approved profile. Whether you are a Ham Radio operator chasing rare low-band DX or a Director of an Emergency Operations Center (EOC) requiring a resilient 160-6M backup system, the 28' Greyline delivers the performance of a tactical array with the elegance of a patriotic home asset.
