HF Vertical Antenna · 160–6M · No Radials · Made in USA
The 20' DXV — The Benchmark Bare Vertical. All Bands, All Conditions.
The DXV20 is where serious operators start when height isn't restricted and a flagpole isn't the goal. At 20 feet, the VDA design opens across the full HF spectrum with genuine low-angle radiation — no flag hardware, no HOA paperwork, just clean RF performance from a radiator that does exactly what it's engineered to do. Return current flows through the lower element, not through soil, significantly reducing ground coupling. No radials. No excuses.
Field Report
"I tested it with a 200mw WSPR transmitter and reached Antarctica, Australia, and more. If the signal is around, it captures it."

The Physics
Why No Radials — and Why It Works
Traditional quarter-wave verticals feed at the current maximum at the base — pushing maximum I²R loss directly through soil. Every ohm of ground resistance sits in series with your radiation resistance, stealing signal before it leaves your yard.
The Greyline VDA is a vertical dipole. Return current flows through the lower element — not through the earth. This design significantly reduces ground coupling and removes your performance's dependency on a soil-based return path. Proper current distribution raises radiation resistance, improving efficiency without a single buried wire.
