FSH3D - Isotropic 3-axial RX Loop Antenna

 

FSH3D - Isotropic 3-axial RX Loop Antenna

 

  • Schwarzbeck FSH3D isotropic H-field antenna for handheld spectrum analyser
  • Schwarzbeck FSH3D
 

The FSH3D consists of three identical, shielded loop antennas, which are aligned perpendicularly to each other. A shielded unit follows, containing the switching and amplifier circuitry, which is directly connected to the N-male output and fed by the Binder-connector with power supply and logic signals to select the desired loop-axis. The pin assignment is ready for operation with the popular handheld spectrum analyzers FSH3/6 and FSH 4/8 from Rohde & Schwarz. A RF-transparent radome cover protects the FSH3D from dust and moisture. Because of its lightweight construction the FSH3D can be directly mounted to the spectrum analyzer. Alternatively the FSH3D can be held manually at its 50 mm shaft (sweeping method) or attached to a mast or tripod using the 22 mm tube (rotation method or raster method).
