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 DX Flagpole is a vertical dipole antenna disguised as a genuine commercial-grade flagpole. One feedpoint covers every HF band from 160 through 6 meters. No buried radials. Return current flows through the lower element rather than through a soil-based ground system, which is why the antenna performs consistently on rooftop, asphalt, frozen soil, or any surface a flag-rated pole can stand on. A permanent property asset your neighbors will compliment and your radio will love.

Technical Specifications & Performance
The VDA Advantage
Return current flows through the lower element, not buried radials. The 2" pole footprint lets you place the antenna in the quietest spot on your property — away from neighbor noise sources, not running toward them.
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 achieve 5/8λ for up to 3.5 dBi of gain over the 1/4λ verticals. Our add-ons get the lower bands there too.
No Radials. No Compromise.
Forget burying wires. Greyline VDA flagpoles are engineered for efficiency without a buried radial field. Rapid deployment, anchored in a single ground sleeve, ready for both DX and EmComm work. NVIS performance on the lower bands. A 2" pole footprint means you can place the antenna in the quietest spot on your property — better signal-to-noise where it matters most.
See why our 24' DX Flagpole outperforms traditional verticals in the radiation pattern at right. Note how the 43' vertical on 15M (orange pattern lines) shoots straight up — power going up instead of out is power not making the DX contact.
Color Key: 80M-red | 40M-blue | 20M-green | 15M-orange
