Equilateral loop height and wire calculator

Calculate full-wave delta-loop wire length, triangle height and base width from frequency, with an adjustable shortening factor for conductor and end effects.

Typical copper wire delta loops use 1.00–1.02. Increase slightly for insulated wire or lower mounting heights.
