Crossed dipole FM broadcasting antenna

Summary

[edit]
Description
English: A broadcasting antenna for an FM radio station on a communications tower on Willans Hill, Wagga Wagga, New South Wales, Australia. These are called crossed dipole antennas, probably the most common type used for FM broadcasting. They consist of two V-shaped dipole elements facing each other; the one on the right driven by a coaxial cable, the one on the left a parasitic element. They radiate a circularly polarized (Cpol) radio signal. Four crossed-dipole "bays", fed in phase, are stacked vertically to increase the horizontal gain, so less of the signal power is radiated into the sky or down toward the ground and wasted.

Alterations to original image: cropped out other parts of tower, increased brightness some.
