Vee Dipole

Long-wire, travelling wave antennas are used when radiation in the forward direction is desired. The wire Vee Dipole antenna is a simple modification of the horizontal long-wire antenna that approximates the pattern, but not impedance behaviour, of a travelling wave antenna. The horizontal long-wire antenna consists of an electrically long wire, horizontally suspended above a ground plane. The Vee Dipole replaces the ground plane with an image wire, and angles the wires to form a V shape. This improves the directivity relative to the horizontal long-wire antenna. This antenna is popular for VHF and UHF applications.
