Description

The Tuned Dipole set model AD-100 is a standard antenna set which operates in the frequency range of 30 MHz to 1000 MHz for E-Field measurements. This set consists of four baluns and was designed accord¬ing 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 select¬ing 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.

Features

• Frequency range - 30 MHz - 1000 MHz
• Low balun loss
• Appropriate for EMI site calibration

Com-Power AD-100 Application

 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.
