| caption1 = A modern form of reflective array is the "bow tie" [[Ultrahigh frequency|UHF]] [[television antenna]].  This example has two dipole driven elements in front of a grill reflector.  The "bow-tie" dipoles, consisting of two V-shaped elements, have a larger bandwidth than ordinary dipoles, allowing the antenna to cover the wide UHF television band. This example is installed for reception of vertically polarized TV transmissions.

| caption2 = Enormous reflective array antenna of the [[Duga radar|Duga]] or "Steel Yard"  [[Over the horizon radar|over-the-horizon]] (OTH) radar system, Chernobyl, Ukraine, part of the Soviet early-warning network.  It transmits at frequencies between 7 and 19 MHz.  The pairs of cylindrical cages at right are the [[half wave dipole]] driven elements.  Behind them is a reflector screen of horizontal wires, just visible in center.
