Tuned half-wave dipoles have been among the most important antennas from thebeginning of rf-technique. The characteristics of half-wave dipoles havebeen calculable very early using the Maxwell and Hertz equations. Therefore the halfwave dipole became a reference antenna. The ideal (lossless) half-wave dipole has anisotropic gain of 2.15 dBi and an impedance of 73 Ohm. The directional pattern is circular inthe H-plane, "8-shaped" in the E-plane with the maxima perpendicular on the dipole axis.The half-power beamwidth (-3 dB) is approx. 78°. The impedance of real dipoles isdepending 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 30MHz to up to approx. 4 GHz. The dipole elements are length variable (telescopic) orwith fixed length, the latter especially above 1 GHz. The most important applications aretest site evaluations (NSA, normalized site attenuation) and the determination of ERP(Effective Radiated Power) respectively EIRP (Effective Isotropic Radiated Power).

AD-100 -
Com-Power Corporation
The Tuned Dipole Antenna model AD-100 is a reference antenna set specified in many EMC standards. It is used in the frequency range of 30 MHz to 1 GHz. This set consists of four baluns and was designed according to American National Standard C63.4. This reference antenna set is used for EMC test site calibrations and for calibrating other antennas, because it is considered a standard antenna according to ANSI C63.5 standard.

SNA600a -
Lectrosonics, Inc.
The SNA600 antenna is a versatile tool for use with wireless microphone receivers or IFB transmitters. The center frequency of its 100 MHz bandwidth is tunable from 550 to 800 MHz. The frequency is set by adjusting the dipole elements using the scale printed on the body of the antenna. The elements fold for storage.
