HOA Stealth Flagpole Antenna · 160-6M · No Radials · Made in USA
The DXF20 — Twenty Feet That Read as a Flagpole on Almost Any Street.
The DXF20 works every band, 160 through 6, from a single feedpoint with no radials and no ground system. Twenty feet fits a residential lot cleanly and reads as exactly what it is: a flagpole, with HOA documentation in the box.
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, with no radials in your yard. How height pays →
Why a Flagpole Antenna?
Most HOA CC&Rs explicitly permit residential flagpoles. On a DXF, the pole itself is the antenna, so there is nothing added to see — no stubs, no loading coils, no radial wires. From the street, it is a flagpole. A handsome one.

"I ran a defense antenna company for 7 years. I am very impressed with the look, quality, machining, and part fit. It is a professional-grade product." HOA approved. FT8 DX confirmed to Hawaii, South America, Europe, and Africa.

"I installed the 20-foot flagpole, worked through the connector setup, and it worked on all bands. In one week I had 241 reports across 29 countries — Europe, Africa, and South America — on just 60 watts, FT8 and CW."

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.

You supply coax for the run to your shack and a tuner, in the shack or at the antenna. Both are below, and both save you money in the same cart.
Built for Real Weather
Every DXF is engineered to ASCE 7-10. The flag is the dominant wind load, which is why the two columns differ; stowing it returns the pole to its bare-vertical rating.
| Model | Flag Up | Flag Down |
|---|---|---|
| DXF12 | 100 MPH | 155 MPH |
| DXF16 | 75 MPH | 115 MPH |
| DXF20 | 60 MPH | 90 MPH |
| DXF24 | 50 MPH | 70 MPH |
| DXF28 | 35 MPH | 55 MPH |
Ratings per ASCE 7-10. Lower the flag when weather threatens. With the 9' whip, lower the whip too: the tilt-up base makes that a two-minute, one-person job.
A note on diameter: a thicker pole is not automatically a stronger one. Wind force scales with projected area, so doubling a pole's diameter roughly doubles the load it must survive. At 20 feet, the 2-inch Greyline presents 3.33 square feet of wind surface. A wind rating without a cited standard is a guess dressed as a spec — ours are printed above.

Tilt-Up Base — $25 Off
Lower the whole antenna to waist height alone, in minutes — change the flag, check the hardware, add the whip, or lay it down before a storm.

Nine more feet on top turns the DXF20 into a Skyline 29: more length for 40 and 80, and bonus gain moving to 17 meters. The flag and whip fly together.

Both placements work, and almost any decent-size ATU will do. The LDG RT-100 remote is the easy, affordable starter — weatherproof, powered over the coax.

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.
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 DXF20 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.
