Associated Radiated RF Equipment



The ABF-900A is a broadband, linearly polarized Biconical Dipole Antenna with collapsible elements, operating over the frequency range of 25 MHz to 300 MHz. Each full-size biconical element (54 cm cage diameter) collapses to a maximum diameter of 5 cm for easy transport/storage.

 The ABF-900A Biconical Antenna is intended for use as an EMI test antenna for qualification-level regulatory compliance measurements (FCC, CE, Mil-Std, RTCA DO160, FDA, SAE Automotive, and similar applications).

The ABF-900A can also be used in conjunction with an RF power amplifier (up to 50 watts) to generate RF fields associated with radiated immunity tests.

In addition, a pair of ABF-900A Biconical Antennas can also be used for Normalized Site Attenuation (NSA) calibrations of Open Area Test Sites (OATS) or SemiAnechoic Chambers (SAC) using the Geometry Specific Correction Factors (GSCF) given in Tables G.1 through G.3 of ANSI C63.5, as its physical dimensions conform to the minimum and maximum values given in Figure G.1 of ANSI C63.5 (Dimensions of biconical dipole antennas evaluated for numerical correction). If biconical antennas have dimensions which do not conform to these min/max values, the given GSCF values can not be used, and would need to be determined by performing GSCF calibration on a Standard Antenna Calibration Site (SACS) as described in Annex H of ANSI C63.5.

Notwithstanding the above applications, the ABF-900A can also be used for test site comparisons, shielding effectiveness tests of large enclosures, field monitoring, site surveys and other general purposes.
