Key facts

  • Operating frequency range from 20 MHz to 20 GHz
  • For locating transmitters and interference sources
  • Frequency extension with downconverter for R&S®PR200
  • Provides standard interfaces for integration with third-party radio systems
  • Exchangeable antenna modules

Portable antenna with downconverter

The R&S®HE400DC handheld directional antenna with downconverter extends the frequency range of the R&S®PR200 portable monitoring receiver from 8 GHz to 20 GHz. The antenna and the R&S®PR200 are used to locate transmitters and interference sources. Bearings are found by manually pointing the antenna in the direction where the signal is strongest.
The antenna consists of an antenna handle, a customized receiver cable set and different antenna modules that can easily be attached using a locking ring. Six different antenna modules are available for reception of vertically or horizontally polarized signals.

Features & benefits

Distinct directional pattern

For unambiguous measurement results  

The directional antenna modules for the R&S®HE400DC feature distinct directional patterns, so that a clear direction can be determined by pointing the antenna towards a signal source.
When in reflective surroundings, multiple measurements from different locations may be needed.

Wide dynamic range

Thanks to switchable active and passive modes (LNA on/off)  

A built-in low-noise amplifier (LNA) can be activated to increase system sensitivity. In passive mode, the amplifier is bypassed and the antenna can also be used near powerful transmitters

Very wide frequency range in a compact size

For easy handling  

The modularity of the R&S®HE400DC together with its individual antenna modules enable a very compact solution.
Operators can cover the wide frequency range of 20 MHz to 20 GHz with a portable system.

Automatic detection of antenna module/polarization

For carefree operation  

The R&S®HE400DC detects the attached antenna module and its polarization. The data is sent to the connected R&S®PR200 portable monitoring receivers. The receiver uses this data to automatically select the correct antenna factor table. The operator does not have to change this manually. There is no risk of measurement results being wrong because of an incorrect antenna factor table.

Trigger button for external receiver

For releasing a measurement  

The R&S®HE400DC microwave handheld directional antenna features a trigger button for starting a measurement. The connected R&S®PR200 portable monitoring receiver performs the measurement and stores the results. The user can instantly start measuring a signal without operating the receiver.

Fatigue-free operation

Antenna design and material keep weight to a minimum  

The R&S®HE400DC microwave handheld directional antenna is low weight and easy to handle. It even comes with a comfortable arm rest that minimizes operator fatigue even when measurements take somewhat longer.

GNSS receiver and electronic compass included

For valuable additional information  

When dealing with signals of interest, knowing the strength, on-air time, the direction of origin and receiving location are all important. The R&S®HE400DC uses GNSS data to provide the operator’s location and electronic compass data to provide the direction of the antenna. This information is forwarded to the receiver and can be stored together with the measured signal data.
