HF Vertical Antenna · 160-6M · No Radials · Made in USA

The DXV20 — Every Band, on Any Surface.

The DXV20 works every band, 160 through 6, from a single feedpoint with no radials — a clean 2-inch pole that goes in on soil, rock, or a rooftop and depends far less on what is under it than a radial-fed vertical does, rated 90 MPH year-round.

Modeled gain: in NEC modeling over average ground, the 20-foot runs ahead of a textbook quarter-wave on full buried radials across 20 through 10 meters — strongest on 10, about +3.2 dBi — and within a decibel or so of it on 30 and 40. How height pays →

First Contacts

"Very sturdy with beautiful looks! First 3 HF contacts were Japan on 10 and 17 meters from Tucson."

— Andrew Croft · 20' HF Vertical · Verified Owner

Why No Radials — and Why It Works

A traditional quarter-wave vertical feeds at its base, so every ohm of ground resistance sits in series with the antenna and steals signal before it leaves your yard. The Greyline VDA is a vertical dipole: return current flows through the lower element, not a buried radial field, so the antenna stops depending on your soil. One feedpoint, every band.

Before you install, run a noise audit. A 2-inch pole goes wherever you choose. Walk the property with a battery AM radio tuned off-station, find the quietest spot, and put the pole there.

From the Reviews — Four Owners, Five Stars

Every verified review of the 20-foot vertical is five stars. What they say is more useful than the number.

“In short, if I can hear them, I can work them even through some serious pileups. I am particularly impressed (and surprised) with 6M performance ... my noise level is also several S-units lower than with my former 1/4 wave trap vertical which makes a real difference!”

— Craig, W3GF · Albania, Peru, Ecuador, Brazil, Italy, Spain on 100 watts · Verified Owner, 2019

“Fit and finish is top notch. First contacts once installed were Vietnam and Tuvalu (4 bands) from Eastern NC!”

— Christopher · 20' vertical with the 9' whip, no HOA (“rather I'm the HOA on my farm”) · Verified Owner, August 2026

“My wife began using FT8 and collected QSOs with 29 countries on multiple bands within a week. I was able to reach Australia, which showed a distance of 10,000 miles. The antenna is in my back yard, close to my house and neighbors say they don't notice it.”

  • 7-Year Warranty

You supply coax for the run to your shack and a tuner, in the shack or at the antenna. Both are below. Add assembled coax to this cart and it's 10% off automatically.

Built for Real Weather

Engineered to ASCE 7-10: 90 MPH, year-round, with nothing to raise or lower. The 2-inch 6061-T6 section is engineered for the load it carries: wind force scales with projected area, so a bigger section only comes out ahead when the whole pole is engineered for it. For exposed, windy sites there is the 28' HD on 3-inch sections. A wind rating without a cited standard is a guess dressed as a spec.

Before You Order — Answered

When does it ship?

Within days, free to the USA and Canada, in more than one box with its own tracking. Call 435-200-4902 for a specific date.

Do I need a tuner — will my radio's internal tuner work?

You need a wide-range tuner: the VDA presents a different impedance on each band, which is how it covers 160-6M with no traps and no radials, and most built-in tuners only handle about 3:1. In the shack or at the antenna, both work, and almost any decent-size ATU will do. For long digital runs, check your tuner's duty-cycle rating.

What coax should I run, and how long?

Measure radio to feedpoint and add about 15 percent for routing and a service loop. LMR-400 class is the sweet spot at HF; LMR-600 earns its premium past 100 feet, at legal limit, or buried. Assembled runs in 25, 50, 70 and 100 feet are 10% off in the same cart as the antenna.

How hard is installation?

Most operators are on the air the same afternoon: dig a post hole, assemble the sections, drop it in, run coax, connect the tuner. Questions during install? Call 435-200-4902.

What does the 7-year warranty cover?

If it fails under normal operating conditions, we make it right. A customer's antenna fell in a severe ice storm — we sent a replacement immediately.

The DXV20 Ships Free to the USA and Canada.

Scroll up and add it to your cart — or call and talk it through first. We would rather you order the right height than the nearest one.

20' antenna with 9' whip

Fit and finish is top notch. First contacts once installed were Vietnam and Tuvalu (4 bands) from Eastern NC! I ordered the 20' DSV with the 9' whip. No HOA (rather I'm the HOA on my farm:). Talked to Jon K2LA about the truck between the 2" section and the whip and he told me they're developing an aluminum cap for the transition rather than using a truck. I'm looking forward to swapping for that.

I am having difficulty tuning 6m and 160m; all others work fine with my LDG AT1000Pro2 tuner. I also notice the receive is around 2 S units quieter than my OCF Dipole. Still readable but leaves me scratching my head as to why. Perhaps it's me or the conditions in my yard. I am using LMR400 and a Polyphaser. Could be the loss introduced by the added connections.

I ordered the 4 foot extension and the tilt whip. They shipped today. I'm hoping they will make an operational difference aside from the ease of putting it up and taking it down.

Busy company. You need a little patience when communicating with them. Automated answering service picks up when you call. Best to send a clean e-mail from their "contact us" link on the web site.

Edited my review (5 stars) after Jon K2LA's very thorough explanation.

Christopher, Vietnam and Tuvalu on four bands from Eastern North Carolina --
those are serious Pacific paths, and they answer most questions about this
antenna before I type a word. Thank you for the detailed report. Let me take
your three puzzles in order, because the next reader will have them too.

The quiet receive is the one to reframe: quieter is not deafer. Your OCF
dipole is a horizontal wire using its coax as part of the antenna -- which
means it hears your house, your neighbors' switching supplies, and every
bit of common-mode trash along the feedline. The vertical, choked at the
feedpoint, hears less of all that. The honest test is never the S-meter --
it is signal-to-noise. Same station, both antennas: if he is as readable or
better on the Greyline while the meter reads lower, your noise floor
dropped, and that is the feature, not the fault. You already wrote the
evidence yourself: 'still readable.' Watch FT8 SNR numbers side by side
for a week and the meter mystery usually solves itself.

Six and 160 are the two ends of the rope. First check that your tuner
covers 54 MHz at its rated range -- not every desktop auto does, and 6
meters is outside several of them. On 160, a 29-foot radiator is working
hard; dress the ladder line straight and clear -- no coiled slack, off the
ground, off metal -- because coiled balanced line is exactly what pushes a
marginal 160 match out of a tuner's reach. Your 4-foot extension, shipped
today, helps the low end honestly but modestly.

The aluminum transition cap: you are on the list, as promised.

And the fair hit on patience: guilty, with an explanation. Every antenna is
hand-built to order by a small shop, and the same hands that answer the
phone are on the bench. Your instinct is right -- a clean email through the
contact page gets the fastest, most complete answer we can give.

Enjoy the tilt base -- and when the extension goes on, I want the Tuvalu
rematch report. Bands are up and down this month as Cycle 25 slides
down the other side of it's world class peak. The pleasure is ours, Christopher.

IMPRESSIVE IMPROVEMENT

This is an antenna I wish I would have purchased sooner. We live in an HOA with a small lot and some restrictions on antenna placement and height. We had a small vertical antenna mounted to our fence, but had limited places to install grounds and could only put two in place along the fence line. We could only receive 40M, sometimes 20M, and both had to be tuned and adjusted at the antenna. This year, those bands began generating high SWR. I was able to determine the wiring and connections were all good but the antenna was failing and we would miss out on the new solar cycle. We ordered a 20' Greyline, without the flag mount options, along with an LDG 100W external tuner. Due to a backlog in supplies, it took many months to process my order, and when I paid with a credit card it was cancelled the following month because they could not ship it within 30 days to process my credit card. I called and they no longer had any 20' antenna packages to ship at that time, but they agreed to ship me a 24' for the same price without further delay. That was still not going to be visible from the street above my home which is an HOA requirement, so I agreed. After receiving the equipment and installing it, I was amazed. 40M, 20M, 12M, and 10M bands were all below 1.5 SWR. 30M was an impressive 1.1 SWR. Unfortunately, I could not tune 80M, 17M, or 15M due to high SWR. Quite possibly this is an issue with the LDG tuner. We have reached far away with this antenna, and my wife began using FT8 and collected QSOs with 29 countries on multiple bands within a week. I was able to reach Australia, which showed a distance of 10,000 miles. The antenna is in my back yard, close to my house and neighbors say they don't notice it. While I could have installed it in the front as a flagpole, I would have to re-rout all of my wiring to the front of the house. This is an impressive antenna. If I were to do this again, I would like to have purchased an already assembled ladder-line to PL-259 adaptor as assembling the provided kit proved somewhat challenging without a drill press which I no longer have after downsizing a few years ago, and having to modify the clamshell case so that it would fit over the PL-259 component. The RF-choke required weather proofing so I ended up purchasing 1-1/2" waterproofed shrink tube that seemed expensive for the length needed. In the end, it all worked well when connected. I fully recommend this antenna.

Wow! So great to hear that you and the XYL both are enjoying the bands together. Let's get those other bands working. Likely a ground issue we can resolve. *We've already called him for a few testing exercises to get things dialed in. Ham Radio is fun again! Pass it on... 73 Greyline Performance

After 3-months, impressive performance, SWR 1.8:1 on 75M-6M, busting pile-ups, & surprisingly...

Hi Jon at Greyline!

After using the Greyline 20’ OCV for several months I wanted to tell you how happy I am with its performance!

With a little tweaking of the installation, I now have matches of no greater than 1.8 to 1, 75M thru 6M. (using the LDG RT-100)

Even with the poor band conditions, we are currently experiencing, I have worked some nice DX….Albania, Peru, Ecuador Brazil, Italy, Spain and most other European countries with great reports on 100 watts from the TS-890. Nothing too exotic yet but I have not really worked at it either.

In short, if I can hear them, I can work them even through some serious pileups.

I am particularly impressed (and surprised) with 6M performance. I have had good reports as far as OK and ME. Really looking forward to improving conditions as the next sunspot cycle ramps up!

Thanks for the great customer support and info!

73, Craig W3GF

PS. I forgot to mention that my noise level is also several S-units lower than with my former 1/4 wave trap vertical which makes a real difference!
