Before You Dig

Step 0: Run a Noise Audit

The VDA’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 on 160 meters — running toward every noise source on the property. The VDA goes where you put it. So before you dig, find the right spot.

The Noise Audit — 10 Minutes, Massive Payoff

1.  Grab a battery-powered AM radio — no connection to house wiring, that’s important.
2.  Tune off any broadcast station so you hear only noise, no signal. Daytime for less noise, Evening for when everyone is home and everything is on.
3.  Walk the property — front yard, back yard, side yards, corners.
4.  Note the quiet zones (away from the meter, HVAC, neighbor’s panel, LED lighting).
5.  Note the loud zones — near anything switching or motorized.
6.  Install in the quietest spot your lot allows. Your on-air experience will be much higher quality.

Footprint. Noise. Smart, Strong, Elegant.

Step-by-Step

Building the Flagpole Antenna — Assembly Order

Before you start: Confirm you have the total height of your antenna plus an extra 3 feet for ground insertion. All hardware should be pre-attached — there should be no loose hardware loose in the box. You will also have a Feedline Kit and, for DXF models, a Flag Kit.

Section note: Thicker wall sections go at the lower portion of the antenna. Thinner, lighter sections are for the upper portion. Each section has its splice or transition bolted to it. Remove only the top two bolts (not the lower two — they may be supporting internal components). Lower the next section down, line up the holes, and re-fasten. Tighten all bolts.

1
Ground section: The lowest section is for ground insertion and matches the length of the included PVC sleeve. It can be identified by the slotted insulator. The slot sits just above ground level for ground installations. Remove the top two sets of bolts, drop the next tube section on, and fasten the bolts.
2
Feedline kit: Have your finished, prepared feedline kit ready. Insert it before fastening the next section. The ladder line with 3 spacers threads through the tubing — spacers sit internally between the insulators. Cut and prep 6” pigtails at the top of your ladder line so each wire can be pulled through its left and right hole for connection to the dipole sections. Pull the ladder line into this second section before fastening it to the third section. You’ll end up with 2–3 feet exiting from the bottom slot holes for feedline connection.
3
Feedpoint section (pro tip): This section has two round holes within the insulator. The two wires from the top side of the ladder line connect here — one wire to each side of the dipole. This is the antenna’s feedpoint. Get this right and everything else is straightforward.
4
Noalox on all metal-to-metal connections. Apply Antenna Grease (Noalox) wherever aluminum meets aluminum. This preserves the connections and prevents corrosion over time. Available at any hardware store for about $5. Don’t skip this step.
5
Permanent installs: Consider using Loctite or similar on the lower bolts — wind movement over time can loosen them naturally. Alternatively, plan to inspect and re-tighten during a season-check. Both approaches work fine in practice.
