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.
VDA physics validated by Robert J. Zavrel W7SX · Antenna Physics: An Introduction (ARRL, 2020) · John D. Kraus W8JK · Antennas (McGraw-Hill)

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.
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.
The No-Radials Advantage: Reliable & Ready
Forget burying wires. Our Vertical Dipole Antennas (VDA) and DX Flagpoles are engineered for efficiency without a radial field. This robust, free-standing design offers rapid deployment and critical reliability, making it a top choice for both DXing and Emcomm professionals. With a native NVIS pattern included and a lower noise floor owing to the no-radials smaller footprint you'll hear the weak signals others miss—when it matters most.
Note: See the 43' vertical on 15M (orange pattern lines) shoots straight up? Not good for DX.
See why our [24' DX Flagpole] outperforms traditional verticals in the real world.
