- 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. |
