What is the approximate overall length of a delta loop antenna?

A delta loop antenna operates on the exact same electrical principle as a quad antenna. Both are closed, full-wave loops. The primary distinction is purely geometrical: a delta loop is shaped as a triangle, while a quad loop is a square. Regardless of whether the loop is shaped like a circle, square, or triangle, the fundamental rule for these single-element loops is that the total length of the wire forming the perimeter remains approximately one full wavelength.
