HF Vertical Antenna + Remote ATU Bundle · 160–6M · No Radials · Made in USA
The DXV24 Bundle — Complete System. On the Air Fast.
The DXV24 is the choice for operators who want real low-band improvement. Four additional feet of aperture over the DXV20 delivers a measurable advantage on 40 and 80 meters. No radials. Deploys on any surface. Suitable for EOC facilities, commercial rooftops, and large residential lots. Paired with the LDG RT-100 remote ATU at the antenna base. You supply coax. That’s it.
Why Bundle?
The LDG RT-100 mounts at the feedpoint — where the tuner belongs for minimum feedline loss. Powered over coax — no extra cable runs. 125W, 160–6M, weatherproof. Buying the bundle saves versus purchasing separately, and the system is spec’d together from the start.

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. Covers 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. Achieves 5/8λ geometry on 12 meters, near 1/2λ on 17 meters. Meaningful aperture advantage on 40 and 80 meters.

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.

Common Questions
Before You Order — Answered.
What’s the current lead time and availability?
We ship from stock — same or next business day when available. Peak season may carry 1–3 week queue. Current lead time 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. That’s it.
✓ VDA Radiator (your chosen height)
✓ RF Choke & Precision Feedline Hardware
✓ Ground Sleeve Kit — in-ground, tower, roof, deck, dock compatible
✓ LDG RT-100 Remote ATU — 125W, weatherproof, base-mounted
✓ Assembly Manual & Tuning Guide
✓ 7-Year Performance Guarantee
Complete system — antenna and ATU included. You supply coax only.
The bundle includes the LDG RT-100 — what power level does it handle?
The LDG RT-100 mounts at the antenna base, powered over coax — no extra cables. 125W, 160–6M, weatherproof. Like all ATUs, it carries a reduced power rating for 100% duty cycle digital modes — check the spec sheet for your operating style. Running above 125W? Source a higher-power ATU for your needs. The antenna handles any power level and any mode without restriction.
Are there other bundle configurations available?
The standard bundle pairs your antenna with the LDG RT-100 (125W). For higher power requirements, contact us — we can configure bundles with the higher-power ATU or equivalent. Contact us →
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.

What does the 7-Year Guarantee cover?
Seven years of performance coverage. If it fails under normal operating conditions, we make it right. No questions asked. A customer’s antenna fell in a severe ice storm — we sent a replacement immediately. Full terms at 7-Year Warranty Policy →
