מאפיינים מרכזיים

SignalShark ADFA 1 and ADFA 2 are Automatic antenna finder with Frequency range 200 MHz up to 2.7 GHz with ADFA1 and Frequency range 10 MHz up to 8 GHz with ADFA2. Be aware that the SignalShark support manual DF (Direction finding) via manual antennas available at the datasheet.

ADFA – Automatic DF Antenna
It is often necessary to locate the position of a signal transmitter once the signals have been detected and analyzed. SignalShark supports the new Automatic Direction Finding Antennas (ADFAs) from Narda, allowing quick and reliable RF signal localization automaticaly.
It assist:

It assist:
  • Managing frequency bands.
  • Quickly and reliably search mobile networks for interferences
  • Monitoring communication at borders.
  • Protecting areas and signal reconnaissance.
  • Single channel, automatic direction finding antenna with omnidirectional reference antenna element in the center
  • DF Method: Watson-Watt and correlatives Interferometer
  • DF accuracy at ADFA2 only – f < 200 MHz: < 1.5° RMS (typ).
  • DF accuracy: f > 200 MHz: < 1° RMS (typ)
  • Built-in electronic compass
  • Built-in GNSS receiver with antenna and PPS output
  • ADFA 1:Automatic DF-Antenna for Mobile Operators, 200 MHz to 2.7 GHz
  • ADFA 2: Automatic DF-Antenna, 10 MHz to 8 GHz
  • RF-Cable, 9 kHz – 8 GHz, N to SMA, 50 Ohm, 5 m*, “Low-Loss”
  • ADFA Vehicle Mounting Kit
  • Option, Automatic DF antenna control, Bearing View

Manual Direction/Location finding available using manual antennas, but it is more complicate.
