Rohde & Schwarz HE300
20 MHz to 7500 MHz Active Directional Antenna

Unambiguous direction finding, i.e. distinct directional pattern with the receive maximum pointing to the front in the frequency range from 20 MHz to 7.5 GHz
Maximum of the antenna output signal serves as a directional criterion (maximum direction finding)
Handy size despite extreme broadband capability
Fatigue-free operation due to the antenna design and the material used, which keep weight to a minimum
May be used for vertical and horizontal polarization in the frequency range from 20 MHz to 7.5 GHz
Wide dynamic range due to switchable "Passive" and "Active" mode
May be mounted on a tripod (¼" mounting thread)
Power supply by standard AA batteries or rechargeable batteries

With its Rohde & Schwarz HE300 20 MHz to 7500 MHz Active Directional Antenna its small size and low weight, the Active Directional Antenna R&S HE300 is ideal for portable use.

In conjunction with portable receivers (e.g. R&S PR100) the R&S HE-300 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 HE 300. 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.
