Batwing

Overview

Batwing, or Super Turnstile antennas are a specialized type of crossed dipole antenna, a variant of the turnstile antenna. Two pairs of identical vertical batwing-shaped elements are mounted at right angles around a common mast. Element “wings” on opposite sides are fed as a dipole. To generate an omnidirectional pattern, the two dipoles are fed 90° out of phase. The antenna radiates horizontally polarized radiation in the horizontal plane.
