​The radiation pattern is omni directional in the H plane, allowing the antenna to receive signals from every direction around the axis. The range covers most wireless bands worldwide, and is designed for the lowest possible VSWR across the range of operation. The antenna exhibits better than 2:1 VSWR for most of the range, and never exceeds 5:1 above 1 GHz. The small size of the antenna enables it to be used for amplifier harmonic measurements when performing tests per IEC 61000-4-3. It is also ideal when performing the TDsVSWR test as per ANSI C63.25 standard.

Key Product Information

​​​Frequency Range

The antenna covers a frequency range of 1 GHz to 18 GHz, making it ideal as a receive antenna for performing the site VSWR chamber validation method per CISPR 16 standard.


The typical VSWR for the model 3183B is less than 2:1.
