Rohde & Schwarz HE300

Portable directional antenna for tracing signal transmitters and interference sources

In conjunction with portable receivers (e.g. R&S PR100) the R&S HE300 is used for localizing transmitting and interfering sources. The direction of signal sources is found by pointing the antenna towards the direction of maximum signal voltage.

The frequency range from 20 MHz to 7.5 GHz is covered by three exchangeable antenna modules delivered with the R&S HE300. Each of these modules has a distinct directional pattern. The modules do not have to be tuned within their frequency sub-ranges. A fourth module (R&S HE300HF for 9 kHz to 20 MHz) is available as an option.
