Batwing antenna

A batwing or super turnstile antenna is a type of radio antenna named for its distinctive shape which resembles a bat wing or bow tie. Stacked arrays of batwing antennas are used as television broadcasting antennas due to their omnidirectional characteristics. Batwing antennas typically generate a horizontally polarized signal. The advantage of the "batwing" design for television broadcasting is that it has a wide bandwidth.
