R&S®DDF255 Digital Direction Finder

Accurate direction finding with measurement and analysis capabilities in a single unit

Applications

Mobile radiomonitoring and radiolocation

The R&S®DDF255 is optimally suited for integration into vehicles:

  • High integration density: compact dimensions of only four height units and 19" width
  • Flexible power supply: powering from AC source or optionally from DC source
  • Front panel control: alternatively, operation via front panel without using a PC
  • Multiple antenna inputs: in the VHF/UHF range up to three DF and/or monitoring antennas can be connected without an external switch being required

The DF and monitoring antennas connected to the R&S®DDF255 have a decisive impact on its performance. In this area, Rohde & Schwarz offers solutions that meet the specific requirements of mobile radiomonitoring and radiolocation.

R&S®ADD295 VHF/UHF wideband DF antenna

Previously, two DF antennas were required to cover the entire VHF/UHF range. This resulted in additional reflection, particularly with systems mounted on vehicle roofs. The R&S®ADD295 solves the problem. It covers the entire VHF/UHF frequency range with two antennas in the form of concentric dipole circles nested in one another. This solution takes up only half the space on the vehicle roof.
