HF Vertical Antenna + Remote ATU Bundle | 160-6M | No Radials | Made in USA

The DXV28 + ATU Bundle - Complete System, On the Air Fast

The tallest vertical Greyline builds, paired with a weather-sealed remote tuner at the feedpoint. Twenty-eight feet of vertical dipole covering 160 through 6 meters, no radials, no flagpole hardware. At 28 feet the geometry reaches 5/8-wave on 15 meters. Deploys on any surface. Add the LDG RT-100 remote ATU and the only thing you supply is coax.

Why the Bare Vertical

The flagpole version exists to satisfy an HOA. If you do not have one, the flag is just wind load. The DXV carries the same VDA core, the same aluminum, the same guarantee, and holds its full 55 MPH rating permanently, because there is nothing to lower when weather arrives.

Band Coverage

160-6M

All HF bands. One antenna, one tuner.

Wind Rating

55 MPH

ASCE 7-10 engineered. No flag load.

Guarantee

7 Years

Free shipping USA. Sun Valley, Idaho.

"I run 32 feet of DXV at my own station and work Africa and Asia regularly on 10 through 30 meters. This week I am adding the 9-foot whip to it, because there is still more to be had. Go as tall as your lot allows. The improvement across the bands is real, and it is the cheapest signal you will ever buy."

The Physics

Why No Radials, and Why It Works

A traditional quarter-wave vertical feeds at the current maximum at its base, which pushes maximum resistive loss directly through soil. Every ohm of ground resistance sits in series with radiation resistance, taking signal before it leaves the yard.

The Greyline VDA is a vertical dipole. It covers 160-6M from a single feedpoint with no radials. Return current flows through the lower element rather than a buried radial field, which reduces ground coupling and removes the dependency on soil conductivity. That is why a Greyline works on a rooftop, on concrete, on asphalt, and on frozen ground where a radial field is not an option. Modeled gain figures are stated with their reference and band on the aperture page.

The physics behind the no-radial vertical dipole is established, published work. The reference shelf is cited at the foot of this page, and a deeper explainer lives in the Signal Lab.

Before You Install - Run a Noise Audit

The 2-inch footprint is the smallest ground signature of any full-HF 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. Take a battery-powered AM radio, tune off any broadcast station, walk the property, and find the quietest spot. That is where the pole goes.

Full Installation Guide

Feed System Note

The DXV is a balanced VDA and the LDG RT-100 ships pre-configured for base-mount. All ATUs carry a reduced power rating on FT8, Winlink, and JS8Call because of the duty cycle, so check the tuner's digital rating before running full power. The antenna handles the legal limit on every band; the tuner is the only ceiling. See the Tuner and Balun Configuration Guide.

Construction - 6061-T6 Aircraft Aluminum

Outside: 2-inch OD, full length, a uniform profile top to bottom, clean and invisible as an antenna. Inside: the wall graduates where the physics demands it, 0.125 inch through the lower 30 percent where base bending stress peaks, and 0.065 inch through the upper 70 percent where reducing mass at height lowers dynamic wind load. No plastic anywhere. All metal, stainless hardware throughout.

At 28 feet the pole presents 4.67 square feet of wind surface, and the moment arm is at its longest. A 4-inch OD pole at the same height would present roughly 9.3 square feet, twice the load at the height where load matters most. Outer diameter is the variable that reveals everything. A slim section sheds wind that a fat one fights.

Every Greyline wind rating is derived from ASCE 7-10 values using actual geometry and 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 cannot name one, you have your answer.

Common Questions

Before You Order, Answered.

What is the current lead time and availability?

Each antenna is hand-built to order during the current artisan production run. Current lead time is always posted on the Order Status page. Call 435-200-4902 for your actual ship date.

The bundle includes the LDG RT-100. What power does it handle?

The RT-100 mounts at the antenna base, powered over the coax, weather-sealed. It handles 125 watts across 1.8-54 MHz. Like all ATUs it carries a reduced rating on 100% duty-cycle digital modes, so check the spec for your operating style. Running higher power? Call and we will configure a higher-power ATU. The antenna itself handles the legal limit on every band and every mode; the tuner is the only ceiling.

Why a remote tuner at the base instead of one in the shack?

This bundle puts the tuner where it does the most good on a long run, keeping the match right at the feedpoint. That said, a desktop tuner in the shack is a perfectly good choice too, and plenty of Greyline owners run each way with excellent results. The deciding factor is usually the length and condition of your feedline. If you would rather run a desktop unit, buy the antenna on its own and pair it with the tuner you prefer.

Can I mount this on a roof, a deck, or concrete?

Yes, and that is the point of the design. With no radial field required, the antenna does not care what is under it. Ground, rooftop, concrete pad, asphalt, and frozen ground all work. The included ground sleeve kit covers in-ground, tower, roof, deck, and dock mounting.

How difficult is installation, and how long does it take?

Most operators are on the air in under an hour. Set the base, build the sections in 15 to 30 minutes, stand it up, run coax, connect the tuner. All stainless hardware arrives pre-fastened. Assembly documents are at Setup and Manuals. Questions during the install? Call 435-200-4902.

What does the 7-Year Guarantee cover?

Seven years of performance coverage. If it fails under normal operating conditions, we make it right. We have replaced antennas damaged by once-in-a-decade ice storms without argument. Full terms at 7-Year Warranty Policy.

Why This Antenna Works

Every Greyline design decision traces back to named, published antenna physics: Zavrel W7SX, Kraus W8JK, Severns N6LF on ground systems, Maxwell W2DU on transmission lines, Lewallen W7EL on modeling. Not opinions. Cited works.

The full shelf lives under The Signal Lab, The Shelf We Read From in the menu, open to everyone.
