Electroculture Antenna Length Calculator
Calculate passive copper-coil geometry, wire length, approximate resistance, and copper mass from stake height, coil diameter, turns, and wire gauge.
Calculate Geometry, Not Efficacy
This calculator estimates how much copper wire a passive coil design uses. It is useful for documenting an experiment, comparing designs, and avoiding vague treatment descriptions. It does not estimate whether the design will affect plants.

Geometry Notes
The helix estimate treats each turn as a circle plus vertical pitch. Real wire length varies with wrapping tension, stake shape, bends, and how much lead is left above or below the coil.
Formula
The coil estimate uses a helix approximation: one turn is the square root of the circumference squared plus pitch squared. Total per antenna is helix length plus any straight lead. Copper mass and resistance are approximate material calculations from wire gauge.
To make this useful for evidence, save the output with your trial plan. If two garden tests use different coil heights, diameters, turns, or copper gauges, they are not the same treatment.
FAQ
Does antenna length predict electroculture performance?
No. This is only a geometry and materials calculator. It does not claim that a longer coil, larger diameter, or lower resistance causes better plant growth.
What does wire gauge change?
Gauge changes approximate wire diameter, copper mass, and DC resistance for the same length. Those numbers help document a test, but they do not establish an electrical dose or biological effect.
