HOA Stealth Flagpole Antenna · 160–6M · No Radials · Made in USA
The 16' DXF — The Sweet Spot for Most HOA Lots.
The DXF16 is where most operators land — tall enough to open up the low bands with authority, compact enough for the tightest deed restrictions. The Vertical Dipole Antenna (VDA) design returns current through the lower element rather than through soil, significantly reducing ground coupling and delivering genuine 160–6M performance without a single buried radial. Your neighbors see a flagpole flying the colors. You're working DX.

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 ever leaves your yard.
The Greyline VDA is a vertical dipole. Return current flows through the lower element — not through the earth. This design significantly reduces ground coupling and removes your performance's dependency on a soil-based return path. Proper current distribution raises radiation resistance, improving efficiency without a single buried wire.

Structural Engineering
Built for Real Weather
The DXF16 is engineered to ASCE 7-10 structural standards. Federal practice: lower the flag when weather threatens. The flag-down rating is your engineering number.
| Model | Flag Down | Flag Up | Standard |
|---|---|---|---|
| DXF12 | 155 MPH | 100 MPH | ASCE 7-10 |
| DXF16 | 115 MPH | 75 MPH | ASCE 7-10 |
| DXF20 | 90 MPH | 60 MPH | ASCE 7-10 |
| DXF24 | 70 MPH | 50 MPH | ASCE 7-10 |
| DXF28 | 55 MPH | 35 MPH | ASCE 7-10 |
Ratings per ASCE 7-10. Lower flag during approaching weather per US federal flag protocol.
