HF Vertical Dipole Antenna + Remote Tuner · 160–6M · No Radials · Made in USA
The DXV24 + LDG RT-100 Bundle — Vertical and Tuner, One Order.
The DXV24 works every band, 160–6M, from a single feedpoint with no radials and no ground system — that is the headline. At 24 feet the low-band aperture comes into its own, where length is what matters on 40 and 80 meters, and on the upper DX bands the modeled gain runs up to +3.5 dBi. This bundle pairs the bare vertical with the 125W weatherproof LDG RT-100 remote tuner at a discount versus buying them separately — the same VDA core as the DXF flagpole, without the flag hardware, built for rooftop, open-yard, waterfront, and commercial sites.
What's in the Bundle
The complete DXV24 bare vertical plus the LDG RT-100 remote ATU — 125W, weatherproof, DC-over-coax, one-button tuning across 160–6M. The tuner solves the variable-impedance match the VDA presents across bands. Bundle pricing is lower than the two bought on their own.

The field reports below come from operators running the 24' DXF flagpole. The DXV24 shares the identical VDA core and 24-foot geometry — the same antenna without the flag hardware — so the on-air results carry across directly.

Greg Newman, K7GAN — 24' DX Flagpole, 3.5 Years and Several Thousand QSOs
Greg runs the 24' DXF flagpole — the same VDA core and 24-foot geometry as the DXV24 on this page, with the flag hardware added.
Greg installed his 24' Greyline DX Flagpole in a covenant-restricted area three and a half years ago. He's logged several thousand QSOs from it. His longest contact: 12,500 miles on FT8.
“Super quality material, was easy to install and performed better than expected. The DX Flagpole antennas are well worth the investment as they work extremely well, made of highest quality materials that will last for a very long time.”
Why this matters: Three and a half years is enough time for materials to fail, joints to corrode, and design weaknesses to surface. The Greyline 24' DX Flagpole at K7GAN's QTH hasn't done any of those. 6061-T6 aluminum, threaded transitions, and clean RF design carry the antenna through years, not just install day.
Aperture Plus Wire
The 24' Antenna Earns Its Aperture. Don't Lose It In The Coax.
A 24-foot DXV delivers meaningful low-band aperture. The wrong feedline gives that gain right back as heat. Use the Feedline Loss Calculator to see how much of your power actually reaches the radiator on each band — especially 10M and 12M, where loss compounds fastest.
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. 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 approaches 5/8λ on the upper bands for strong low-angle DX radiation, and at 24 feet the added aperture lifts the low bands where it counts.
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
The 24' runs up to +3.5 dBi on the upper DX bands (modeled), with full per-band figures and their reference 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 the smallest ground signature of any full-HF-coverage antenna. 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.

Structural Engineering
Built for Real Weather
Every DXV is engineered to ASCE 7-10 structural standards. With no flag, the DXV carries no flag drag — so it holds a single rating equal to the flag-down figure of the matching flagpole, the strongest case for that geometry. The ratings below are real values for the actual pole. When you compare antennas, the question worth asking is which standard produced the number. A figure you can stand behind in a storm is worth more than a bigger one you can't.
| Model | Wind Rating | Standard |
|---|---|---|
| DXV12 | 175 MPH | ASCE 7-10 |
| DXV16 | 132 MPH | ASCE 7-10 |
| DXV20 | 105 MPH | ASCE 7-10 |
| DXV24 | 82 MPH | ASCE 7-10 |
| DXV28 | 65 MPH | ASCE 7-10 |
Ratings per ASCE 7-10 for the bare vertical. The end customer is responsible for a foundation suited to the site.

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.
A note on diameter, because it's widely misread: a thicker pole is not automatically a stronger one. Wind force scales with projected area — the width the wind actually sees — so doubling a pole's diameter roughly doubles the wind load it must survive, before accounting for the extra mass carried at height and the added dynamic fatigue on every gust cycle. The Greyline runs a 2-inch outer diameter precisely because a slim, engineered section sheds wind better than a fat one fights it. Narrower, run correctly, is the stronger answer.
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 which standard they used. If they can't cite one, you have your answer.

Each antenna is hand-built to order during our current artisan production run — typical lead time runs a few weeks, and we expect to return to ship-from-stock as the run completes. Current lead time is always posted on our Order Status page → Call 435-200-4902 for a specific ship date.
How long does shipping take once it leaves Sun Valley?
USA shipping is free. Ground transit runs 2–5 business days from Sun Valley, Idaho. Tracking sent at shipment. International rates calculated at checkout.
What's included — do I need to source anything separately?
Everything to assemble and mount is in the box. You supply coax and an ATU. That's it.
✓ VDA Radiator (your chosen height)
✓ RF Choke & Precision Feedline Hardware
✓ Ground Sleeve Kit — in-ground, tower, roof, deck, dock compatible

✓ 7-Year Performance Guarantee
The DXV ships as a bare vertical. The DXF flagpole models add USA-made flag kit hardware, the HOA Architectural Brief, and the Property Integrity Letter.
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 antenna is available bundled with the LDG RT-100 at a discount versus buying separately. 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.
