BiConiLog Antenna : 3149 | ETS-Lindgren

The ETS‑Lindgren Model 3149 BiConiLog Antenna (ref. 401204) is an ultra‑broadband hybrid log‑periodic and bow‑tie antenna. Designed for EMC radiated immunity testing, it delivers excellent low-frequency performance (down to 80 MHz) and supports compact chamber use with high power input up to 750 W.

Benefits :

• Ultra-broadband range from 80 MHz to 6 GHz.
• Handles up to 750 W continuous power.
• Cross‑polarization rejection exceeds CISPR requirements.
• Compact size ideal for tight chamber environments and portable setups.

Key Features :

• Frequency range: 80 MHz – 6 GHz
• Maximum continuous power: 750 W at 80 MHz
• VSWR (max): approximately 6.5:1 with bow‑tie elements in place
• Polarization: Linear
• Impedance: 50 Ω
• Connector: Type N (female)
• Construction: Rugged aluminum extrusion with powder-coat finish
• Mounting: Center-point stinger or rear-tube mount compatible with ¼‑20 thread
• Calibration: Individually calibrated; includes signed certificate of conformance

Typical Applications :

• EMC radiated immunity testing
• High‑power field generation in compact chambers

Further Information :

• Modeled and tested to ensure structural integrity and repeatable measurements.
• Cross‑polarization rejection better than 20 dB, compliant with CISPR‑16‑1.
• Self‑supporting design with detachable bow‑tie elements for easy setup.
