Broadband, linearly polarized Biconical Dipole Antenna

AB-300M Biconical Dipole Antenna Overview

• Broadband, linearly polarized Biconical Dipole Antenna operating over 25 MHz to 300 MHz.
• Can be used as a receiving antenna for EMI measurements or a transmitting antenna for immunity tests.
• Construction includes improved antenna design and excellent performance.
• Standard antenna elements are corrosion-resistant aluminum powder coated for durability.
• Optionally available collapsible elements made from high-quality, polished aluminum.
• Designed for use as an EMI test antenna for regulatory compliance measurements.
• Can be used with an optional 5 dB impedance-matching attenuator to comply with CISPR 16-1-4 minimum 10 dB return loss requirement.
• Can be used with an RF power amplifier to generate RF fields for radiated immunity testing.
• Can be used for Normalized Site Attenuation calibrations of Open Area Test Sites or Semi-Anechoic Chambers.
• Can also be used for test site comparisons, shielding effectiveness tests, field monitoring, site surveys, and other general purposes.
• Each antenna is individually calibrated per ANSI C63.5 or SAE ARP958 with NIST traceability.
