Two collinear strokes fed from a central gap.
Also known as: Half-wave dipole, Two rods with a gap, Doublet antenna, Dipole radiator
A dipole is two conductors fed at a central gap, and its length is tied to the wavelength — a half-wave dipole is half a wavelength long. That relationship is why antenna dimensions are the most reliable clue to what band a piece of equipment works on.
Denotes a dipole antenna: two collinear conductive elements fed from a central feed point.
Contexts: Electrical equipment
Has its length determined by the operating wavelength, a half-wave dipole being approximately half a wavelength end to end.
Contexts: Electrical equipment
Radiates in a doughnut pattern around its axis, with nulls off the ends, which is why orientation affects reception.
Contexts: Electrical equipment
Two short straight strokes in line with each other, separated by a small gap at the centre where two feed lines connect.
