The DXF is the flagpole version — it looks like a residential flagpole and flies a full-size flag. Ideal for HOA neighborhoods and anywhere aesthetics matter. The DXV is a bare vertical — same physics, no flagpole appearance. Better for rooftop, commercial, or rural installs where the flagpole look isn’t needed. Both use identical VDA technology and cover 160 through 6 meters. The Selection Guide walks through the full decision.

The DXF20 is the most popular for standard suburban lots — it’s the scale most people picture when they think "residential flagpole." Smaller lots, high-wind regions, or townhomes favor the DXF12 or DXF16. If you want maximum low-band aperture (especially 80 and 160 meters), go taller — the DXF24 and DXF28 have a meaningful advantage there. All models cover 160 through 6 meters.

You can use your own tuner! — Consider your power requirement and the ATU power rating, use quality coax, and install your tuner on one end of the coax or the other (at the antenna or on the Radio Desktop. Both remote ATUs and desktop tuners are both widely used with Greyline antennas.

Check the Order Status page for current production status. We build in Sun Valley, Idaho — lead times vary by season and order volume. Current status is always posted there.

Yes — The Greyline VDA is a vertical dipole. Return current flows through the lower element rather than through a buried radial field — significantly reducing ground coupling and removing the dependency on soil conductivity. We've heard RF engineers say that bad-ground (which many of us have) is a good thing. Not everyone can live on the salt water. The antenna's 2-inch pole footprint is the smallest ground signature of any full-HF-coverage antenna. A traditional vertical's radial field extends hundreds of feet at 160 meters, running toward every noise source on the property. The VDA goes where you put it — as far from interference as your lot allows. Some capacitive coupling to ground always exists, but performance does not depend on soil conductivity. You can mount it on a rooftop, asphalt, or frozen ground and it performs identically to a ground-mount. Full physics explanation here.

LMR-400 or equivalent low-loss coax is always a good idea. A 1:1 current-mode RF choke (common mode choke) in front of the tuner is the correct placement — it prevents RF from traveling back down the feedline into the shack or gear. Do not skip the choke. The Tuner Configuration Guide covers exact placement and specs. 

Run a noise audit before you dig. The VDA’s 2-inch pole footprint is the smallest ground signature of any full-HF-coverage antenna — which means you can place it wherever your lot is quietest, not wherever a radial field happens to end up. Here’s how: grab a battery-powered AM radio (no connection to house wiring), tune off any broadcast station so you hear just noise, and walk your property. Note where it’s quiet and where it’s loud — near the utility meter, HVAC units, neighbor’s panel, and LED lighting are typical loud spots. Install in the quietest zone you find. Ten minutes of walking pays off every single day you operate.

One standard 50-lb bag of fast-set concrete is sufficient for most residential installations. Dig the hole 3 feet deep, set the sleeve, fill with concrete, check plumb with a level, and allow 24 hours cure time before loading the pole.

In order of likelihood: (1) Verify the only one 1:1 choke balun is active in the system. (2) Verify you’re using the correct feedline type (coax, not ladder line, for standard installations). (3) Reset the tuner memory and retune from scratch. If still stuck, call us. Remember, some tuners are very small and asking it to take you to 160 may be a tall ask of it. In this case, a larger tuning unit may be more suitable.

All of them — 160 meters through 6 meters from a single feedpoint with an ATU. No band switching, no separate antennas. The OCF feedpoint position is specifically chosen to optimize multiband coverage across the full HF spectrum, including WARC, MARS, military and commercial service bands as well.

Favorably in most residential scenarios. A wire dipole or end-fed needs to be quite a bit higher than your Greyline to achieve the low angle of performance of aGreylilne  — also, horizontal antennas require far more space, is visually obvious, and typically has a worse noise floor due to common-mode pickup on the feedline in addition to close proximity to the neighbors QRN causing devices. The VDA’s balanced feedpoint design significantly reduces common-mode noise. Operators consistently report a cleaner received signal compared to their previous wire antennas.

Yes. The antenna handles 1500W+ continuous — 100W is well within spec. The LDG RT-100 bundled tuner is rated for 125W. If you’re running more than that, step up to a high power tuner.

In most cases, yes — because most CC&Rs explicitly permit residential flagpoles, and the DXF is a genuine commercial-grade flagpole. The antenna function is entirely internal and invisible. We provide a complete HOA approval toolkit including the Architectural Brief, Property Value FAQ, and Commercial-Grade Guide. Full approval toolkit here.

A premium residential flagpole. Polished aluminum, clean lines, flies a full-size American flag. No visible stubs, no loading coils, no radial wires. Operators consistently report that neighbors compliment the installation. Nobody has ever been told their Greyline flagpole looks bad.
