HF Vertical Antennas & HOA Flagpole Antennas · Made in USA · Sun Valley, Idaho

Your neighbors see a flagpole.

Your radio sees 160 meters to 6 meters — no radials, no complaints, no HOA grief.

The Greyline VDA is a genuine commercial-grade flagpole that covers every HF band from a single feedpoint. Return current flows through the lower element rather than through a buried radial field — significantly reducing ground coupling and removing your performance’s dependency on a soil-based return path. A permanent property asset your neighbors will compliment and your radio will love.

Technical Specifications & Performance

The VDA Advantage


Our Vertical Dipole Antenna (VDA) design is balanced against itself, not the ground. This removes the need for complex radial fields while providing a high-efficiency signal that reaches the horizon.

Smart Integration & Power

Designed to handle the legal limit, Greyline systems integrate seamlessly with ATUs at the base or in the shack. This ensures maximum power transfer and continuous 160-6M coverage with minimal loss.

See Tuner & Feedline Requirements →

Optimized for the DX Horizon

For radio ops seeking maximum low-angle gain, our longer Flagpole & VDAs acheive 5/8λ for up to 3.5 dBi of gain over the 1/4λ verticals. Our add-ons get the lower bands there too.
