Key Product Information

​​​​Frequency Range

The frequency range of the model 3148B is 200 MHz to 2 GHz. This makes the 3148B ideal for CISPR 16 testing and other standards based on it, such as CISPR 25.

High Gain

The model 3148B’s design provides a balance between the shortest antenna and the highest possible gain, with a 5 dB average gain over its frequency.


The choice of spacing between booms and the changing element diameter provide excellent impedance of the antenna. This results in a in low VSWR.

Individually Calibrated 

The 3148B broadband antenna is individually calibrated at 1 m per SAE ARP 958 and 3 m and 10 m per ANSI C63.5. This antenna also comes with a signed Certificate of Calibration Conformance.
