The End Fed Half Wave Antenna - gnarc.org
www.gnarc.orgThe most common half-wave antenna is the center-fed dipole, whose impedance is approximately 72 ohms. A dipole is basically a mono-band antenna. It is sometimes used on its 3rd harmonic with coax, or used multiband as a doublet with balun, ladder line and wideband tuner.) If fed off center, say at 30%-70% point, impedance is approximately 200 ohms
