Key Facts
Picture R&S®HE300 Antenna

20 MHz to 7500 MHz

Portable directional antenna for tracing signal transmitters and interference sources

Due to 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®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.

Two different models of R&S®HE300 are available. They differ in the supply and display unit:

Model 02 contains a supply and display unit which comprises the following modules:

  • Compass with turnable graduation ring
  • Antenna electronics with built-in low-noise amplifier
  • Toggle switch for switching between "Active" and "Passive" mode

Model 03 contains a supply and display unit which comprises the following modules:

  • Electronic compass module
  • GPS receiver module with integrated patch antenna
  • Antenna electronics with built-in low-noise amplifier
  • Toggle switch for switching between “Active” and “Passive” mode with the additional feature to detect the state of the switch by the connected receiver, eg R&S®PR100
  • Microcontroller unit for data transfer to the connected receiver, e.g. R&S®PR100, via a serial interface

Furthermore R&S®HE300UK Upgrade Kit is available. It contains all hardware required to upgrade from model 02 to model 03.
