Materials
Every antenna is solid 99.9% pure copper—no plating, no alloy. An 8 mm copper rod base with 4 mm wire, hand-wound clockwise into a tight coil at the top, made to Christofleau's original 1920 specification. Each antenna stands about 12 inches (30 cm) tall above the soil once planted and weighs around 4 ounces (113 g).
Planting Options
No tools required. Push the copper rod 4 inches (10 cm) into the soil until it stands firmly upright. It works in garden beds, raised beds, containers, pots, or greenhouse plots, both outdoors and indoors.
Planting more than one? Space them about 3 feet (90 cm) apart. Plant once and leave it. Works in any climate zone where you can garden.
Care & Lifespan
No batteries, no wiring, and no upkeep—ever. The copper develops a natural patina over time, which is part of the method, not a defect. Wipe with a dry cloth if you like. Built to last a lifetime.
Simple
It's a piece of copper you push into the dirt. That's it. It pulls energy that's already in the air down into the soil, right by your plants' roots. No chemicals. No batteries. Nothing to plug in.
How it reaches your plants
The air around your garden holds a tiny natural charge. Copper is really good at catching it. The coil on top catches the charge, and the rod carries it down into the soil. You know how everything looks greener after a storm? It's that same kind of energy. That little charge can help your soil feed your plants better.
Why it's made of copper
Copper carries energy better than almost any metal. That's why the old 1920 design used copper, bent into a coil. The coil catches the energy from the air. The rod sends it into the ground. No power needed.
Where it came from
Back in 1920, a French inventor named Justin Christofleau made this copper antenna for gardens. He sold over 100,000 copies of his guide. Farmers said their gardens grew like never before. France and Britain even tested it.
Because it's pure copper rather than plated steel, it never rusts. Outdoors it slowly deepens into a warm garden patina, season after season. Plant it once and it's there for life.

Pure copper naturally darkens over time — a patina that makes each piece uniquely yours. Prefer the bright look? A quick clean brings it right back.
Cleaning: Rub with half a lemon dipped in salt for 30–60 seconds, rinse, and dry immediately. For heavier tarnish, soak 15–30 minutes in white vinegar with a teaspoon of salt. Daily wear keeps it naturally polished — your skin's oils do the work.
Keep away from: Chlorine, saltwater, perfume, harsh soaps and chemical cleaners. Take it off before swimming, put it back on after.
Green mark on skin? Completely harmless — it's proof your copper is real, not plated. Washes off with soap and water, and usually fades within a few weeks of wear.
Storage: Store in the dry pouch it arrived in, away from humidity. An airtight bag slows tarnishing even more.
