The Com-Power AD-100 Dipole Antenna Set is a standard antenna set which operates in the frequency range of 30 MHz to 1000 MHz for E-Field measurements. The Com-Power AD-100 set consists of four baluns and was designed according to American National Standard for Calibration of Antennas for Radiated Emissions in Electromagnetic Interference (EMI) Control C63.5.

The dipoles can be tuned to any frequency by selecting the balun for that frequency and adjusting the length of antenna elements to the half wavelength (calculated by 3x108/frequency in MHz/2). The length can be achieved by attaching together pairs of fixed and adjustable elements (lower frequencies) or a pair of adjustable elements (higher frequencies) to each side of the antenna balun. The fixed length elements were designed to minimize drooping, especially at low frequencies where the tuned dipole elements are long. The dipoles are shipped with typical calibration data, which is included in the manual. However, the dipole set can be individually calibrated upon request. The antenna set includes a custom carrying case.

Although broadband antennas such as biconical and log periodic antennas are used for day-to-day EMC measurement, tuned dipoles antennas are still considered the standard antenna. Dipole antennas are not considered the antennas of choice for sweep measurements, because it must be tuned at each frequency. However, dipoles are preferable and in some cases required for site attenuation measurements. It is also considered the reference antenna that can be used to calibrate other antennas operating in the same frequency range.
