Schwarzbeck Tuned Half-Wave Dipoles Data Sheet Overview Dipole Antennas

Tuned half-wave dipoles have been among the most important antennas from the beginning of rf-technique.
The characteristics of half-wave dipoles have been calculable very early using the Maxwell and Hertz equations.
Therefore the half wave dipole became a reference antenna.
The ideal (lossless) half-wave dipole has an isotropic gain of 2.15 dBi and an impedance of 73 Ohm.
The directional pattern is circular in the H-plane, "8-shaped" in the E-plane with the maxima perpendicular on the dipole axis.
The half-power beam width (-3 dB) is approx. 78°.
The impedance of real dipoles is depending on the thickness/length ratio of its elements, typical values are 60-70 Ohm.
Dipoles for industrial applications are available in the frequency range from 30 MHz to up to approx. 4 GHz.
The dipole elements are length variable (telescopic) or with fixed length, the latter especially above 1 GHz.
The most important applications are test site evaluations (NSA, normalized site attenuation) and the determination of ERP (Effective Radiated Power) respectively EIRP (Effective Isotropic Radiated Power).
