HF Vertical Dipole Antenna · 160–6M · No Radials · Made in USA
The DXV24 — Bare Vertical. Serious Low-Band Aperture.
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 the upper DX bands get strong low-angle radiation. Same VDA core as the DXF flagpole, without the flag hardware — a clean 2-inch vertical built for rooftop, open-yard, waterfront, and commercial sites where a bare pole is the right answer.
Why a Bare Vertical?
The DXV is the same vertical dipole as our flagpole series with the flag hardware left off — no visible stubs, no loading coils, no radial wires, no flag. A clean 2-inch pole that disappears against a rooftop, a tree line, or a commercial mast. For operators who don't need the flagpole disguise, it is the most direct path to the VDA architecture.

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.
The Gain Figures, With Their Reference
Full per-band modeled figures and their reference 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 has a 2-inch pole footprint and no radial field at all. 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, because with the flag stowed that is what the flagpole is. A flagpole cannot be stronger than the bare pole it is built from. When you compare antennas, the question worth asking is which standard produced the number.
| Model | Wind Rating | Standard |
|---|---|---|
| DXV12 | 155 MPH | ASCE 7-10 |
| DXV16 | 115 MPH | ASCE 7-10 |
| DXV20 | 90 MPH | ASCE 7-10 |
| DXV24 | 70 MPH | ASCE 7-10 |
| DXV28 | 55 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. The 9' DX Whip is removable in about two minutes with a tilt-up base, so the antenna returns to its published rating whenever the whip comes down.
Complete The Station
One Cart. No Codes.
The tilt-up base and the RT-100 come off automatically when they ride in the same cart as the antenna. Nothing to enter, nothing to remember. The rest are simply worth knowing about.
Coax — Genuine Times Microwave
The antenna is only as good as the line feeding it, and a tired run can eat half your power on the high bands. LMR-400, LMR-600 and Heliax, assembled to length and tested.
Shop Coax →Tilt-Up Base — $25 Off
Two minutes, alone, no ladder. Raise the whip for a contest weekend, lower it Sunday night, service the feedpoint at waist height, drop it before a storm.
View Tilt-Up Base →RT-100 Remote Tuner — $25 Off
A wide-range ATU is required either way. The RT-100 lives at the feedpoint, weatherproof, DC over coax, one-button tuning 160–6M.
View RT-100 →9' DX Whip — A Mode, Not a Commitment
The DXV24 plus the whip is the Skyline 33 — 33 feet of vertical, and the low bands know it. With a tilt-up base it goes up and comes down in about two minutes: run tall after dark or on a contest weekend, then back to a clean 24 feet.
View Whip → Skyline 33 →4' Vertical Extension
Four more feet of radiator, added at the top section. The smallest permanent step up the line — a 24-foot DXV becomes 28 feet of aperture without a new antenna. Ships with the transition splice.
View Extension →316 Marine Hardware
Salt air finds the fasteners first. Every antenna ships with stainless hardware throughout; for waterfront, coastal and dock installs, the 316 marine kit is the grade specified for saltwater service. Fits 12' through 28'.

Built for Where a Bare Pole Belongs
The DXV goes where the flagpole disguise isn't needed — rooftops, open yards, waterfront, towers, and commercial or agency sites. A decade of field experience behind the design.
Rooftop, Yard & Tower
2-inch footprint, no radial field, mounts to ground sleeve, tower, roof, deck, or dock. Find the quietest spot and put it there.

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. Stainless hardware throughout. Threaded transition sections machined directly into the metal — self-aligning, no through-bolting, less total weight.
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.
Common Questions
Before You Order — Answered.
What's the current lead time and availability?
Each antenna is built to order. Current lead time is always posted on our Order Status page → Call 435-200-4902 for a specific ship date.
Does the 9' whip change my wind rating?
Yes. Nine more feet of radiator adds projected area at the top of the pole, where the moment arm is longest. We do not publish a with-whip figure, and you should be skeptical of anyone who does without naming a standard.
What we can tell you plainly: with the whip down, the antenna is the bare pole at the 70 MPH rating printed above. That is why the whip and the Tilt-Up Base belong together. Two minutes, alone, no ladder — up when you want the aperture, down when weather is coming. If your site is exposed, call us before you order a whip and we will talk it through.
How long does shipping take?
Shipping is free — USA and Canada. Ground transit runs 2–5 business days once it leaves a Greyline facility. Tracking sent at shipment. International rates calculated at checkout.
Can I get marine-grade hardware for a coastal install?
Yes. Every Greyline ships with stainless hardware throughout as standard. For waterfront, coastal and dock sites, the 316 Marine Stainless Hardware Kit → is the grade specified for saltwater service. It fits 12' through 28' Greyline verticals — order it with the antenna.
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
✓ Assembly Manual & Tuning Guide
✓ 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, and it takes $25 off automatically when it's in the same cart as the antenna. 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.
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.
