HF Vertical Antenna · 160–6M · No Radials · Made in USA
The DXV20 — The Most Popular Vertical. Full HF Coverage.
The DXV20 is the vertical most operators choose — full 160–6M coverage from one feedpoint, no radials, no ground system, any surface. Twenty feet of aperture covers every band and performs genuinely well across the spectrum. Go as tall as your site allows and you pick up bonus dB on the low bands, but the DXV20 is the height that fits most installs cleanly, and it does serious work on every band. Same OCF VDA physics as the full DXF lineup, in a clean bare vertical for rooftop, deck, and open-yard installs.
Shipping Now: The bench is current — most antenna systems are shipping in under a week. (Please allow up to 3 weeks, as always.)
Not sure this is the right height for your site? Call us at 435-200-4902 and we will spec your system in ten minutes — your surface, your bands, your power, your noise floor. A real person answers, and we would rather talk you into the right antenna than the expensive one.
DXV vs DXF — Same Physics, Different Profile
The DXV is the bare vertical — no flagpole hardware, no flag kit. Same OCF VDA physics as the DXF. Choose DXV for rooftop, deck, commercial, POTA, or any install where the flagpole aesthetic isn't needed. Want the flagpole version? See the DXF20

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. It works every band, 160–6M, from a single feedpoint with no radials — that is the headline. Return current flows through the lower element, not through a buried radial field, significantly reducing ground coupling and removing dependency on soil conductivity. On top of full coverage, the geometry peaks toward 5/8-wave on 10 meters for strong low-angle DX radiation — a bonus on the upper bands, not the whole story.
The physics behind the no-radial vertical dipole is established, published work — the full reference shelf is cited below, and a deeper VDA explainer lives in the Signal Lab for further study.
Gain, Honestly
Modeled gain figures and their references are stated on one sourced page so the numbers stay consistent everywhere. Aperture & Gain — the modeled figures
Before You Install — Run a Noise Audit
The VDA's 2-inch pole footprint is a very small ground signature for full HF coverage. A traditional radial field extends hundreds of feet at 160 meters — running toward every noise source on the property. The VDA goes where you choose. Grab a battery-powered AM radio, tune off any broadcast station, walk your property, and find the quietest spot. That's where the pole goes.

DXV or DXF? Same VDA core. The DXF20 adds flagpole hardware, flag kit, and HOA documents. DXV20 is the clean bare vertical — rooftop, deck, open yard, any surface.
Construction — 6061-T6 Aircraft Aluminum
Outside: 2" OD, full length — uniform profile top to bottom. Clean. Sleek. Invisible as an antenna. Inside: wall graduates where the physics demands it — 0.125" lower 30% where base bending stress peaks, 0.065" upper 70% where reducing mass at height lowers dynamic wind loads. Zero plastic. All-metal. McMaster-Carr hardware throughout.
At 20 feet, the Greyline VDA presents 3.33 square feet of wind surface. That number matters more than most buyers realize: wind force scales linearly with projected area and with the square of velocity, and a wider pole also concentrates more mass at height, increasing fatigue stress on every oscillation cycle. Outer diameter is the spec that drives all of it.
Every Greyline wind rating is derived from ASCE 7-10 structural engineering values — actual geometry, actual math, published methodology. A wind rating without a cited standard is a guess dressed as a spec. Ask any antenna maker for their outer diameter and the standard behind their rating. Ours are both printed above.

Do I need an ATU — will my radio's internal tuner work?
Yes, an external ATU is required. The VDA presents variable impedance across its operating range — that's how it covers 160–6M from a single feedpoint with no traps and no radials. Most internal tuners won't handle the full impedance range on every band.
An external ATU lives in one of two places, and both are right depending on your run. For a short feedline run, a desktop ATU at the radio is the simpler path — it stays warm and dry indoors and you can hear it tune. For a longer run, a weatherproof remote ATU at the antenna base keeps the match close to the feedpoint; the LDG RT-100 is a low-cost 125W fit for that job. Either way, note that all ATUs carry a reduced power rating for digital modes (FT8, Winlink, JS8Call) due to 100% duty cycle heat loading — check your tuner's digital rating before running full power on those modes. Running high power? The antenna handles the full legal limit on every band — the tuner is the only ceiling, and higher-power ATU options are available. Antenna + ATU bundles
Is the ATU bundle the best value?
Yes. Every DXV is available bundled with the LDG RT-100 at a discount. Free shipping USA. Shop all bundles
How difficult is installation? How long does it take?
Most operators are on the air in under an hour. Dig a post hole, build the antenna sections (15–30 min), drop it in, run coax, connect the ATU. All stainless hardware comes pre-fastened — no loose hardware to lose in the grass.
