3140B Hybrid Log Periodic and Bowtie (BiConiLog™)
The Model 3140B BiConiLog Antenna delivers radiated immunity performance in a rugged, compact design for EMC testing.
Free-Standing Broadband Antenna Designed for EMC Radiated Immunity Measurements
The Model 3140B BiConiLog Antenna is one in a series of antennas designed for broadband EMC radiated immunity (RI) measurements. It is composed of a patented T-Bow Tie element design that significantly improves low frequency performance, compared to conventional biconical or other hybrid antennas. These T-Bow Tie elements are easily attached/detached with hand tightened screw knobs, and the antenna is self-standing when placed balun end down on a ground plane.
Note: The Model 3140B BiConiLog is not designed to be used for RE (radiated emissions) measurements.
Key Advantages:
- Frequency Range: 26 MHz to 3 GHz
- Two Year Warranty
- Fits Compact Chambers
- Tough Powder Coat Finish
- Avg. 2:1 VSWR above 80 MHz
- Best EMC RI Performance from 26 MHz to 80 MHz ≤ 300 W to generate 10 V/m above 30 MHz at 3m, 80% AM
