Key Product Information

​​Frequency Range

The model 3143B frequency range covers from 30 MHz to 1 GHz. This frequency range covers the necessary range of emissions testing on a traditional OATS/semi-anechoic chamber setup.

VSWR Levels

Typical VSWR for the 3143B is >3:1 above 70 MHz, an excellent level at this low frequency for an antenna this size.

Emissions and Immunity Antenna

Emission measurements can be performed without having to change antennas. For immunity measurements, the 3143B covers the typical 80 MHz to 1 GHz range.

Flexible Mounting System

The model 3143B comes with a bracket that accepts either a 1/4 in x  20 thread screw or rear stinger mount.
