Wire antennas

Dipoles, loops and long wires: the antennas most operators start with.

The half-wave dipoleThe reference antenna: pattern, impedance and length.The inverted VA dipole with one support and a lower impedance.Fan and trap dipolesCovering several bands with one antenna.Off-center-fed dipolesMultiband operation with a 4:1 balun.End-fed half-wave antennasA half-wave fed through a high-impedance transformer.Long wires and random wiresSimple wire with a tuner: benefits and traps.The folded dipoleWider bandwidth and four times the impedance.Doublets and the G5RVOpen-wire-fed multiband antennas.Full-wave loopsA wire loop with gain and low noise.Slopers and the inverted LWire antennas for one support and the low bands.
