R&S®HF907DC Antenna

SHF Directional Antenna with Down Converter

  • Overview

Key facts

  • It extends the frequency range of portable receivers (e.g. R&S®PR100) up to 18 GHz
  • It allows localization of transmitters or interfering sources by utilizing the distinct directional pattern of a log.- periodic antenna.
  • A version without integrated antenna is also available.

Features

  • Manual polarization switching (horizontal, vertical and 45° slant)
  • Distinct directional pattern
  • Battery operation for portable applications

Specifications

Model Frequency range
R&S®HF907DC 7.5 GHz to 18 GHz

Key facts

  • 7.5 GHz to 18 GHz
  • Broadband directional antenna with down converter

    The R&S®HF907DC SHF Directional Antenna with Down Converter combines two key features into a single product:

    • It extends the frequency range of portable receivers (e.g. R&S®PR100) up to 18 GHz
    • It allows localization of transmitters or interfering sources by utilizing the distinct directional pattern of a log.- periodic antenna. This is achieved by directing the antenna manually toward the direction of maximum receive signal voltage

    The operating frequency range is downconverted to the range below 7.5 GHz in two switchable frequency bands. Preselection filters for each band suppress image frequency and IF breakthrough.

    Due to the use of a rechargeable battery, the antenna is suitable for mobile applications.

features & benefits

  • Manual polarization switching (horizontal, vertical and 45° slant)
  • Distinct directional pattern
  • Battery operation for portable applications
  • Automatic frequency switching (in conjunction with R&S®PR100)
  • Excellent suppression of image frequency and IF breakthrough by means of switchable preselection filters
