Highlights
Narda Direction Finding (DF) Antennas in combination with the Real-Time Handheld Analyzer SignalShark® cover a wide frequency range with highest sensitivity.Each antenna is optimized for sensitivity and directivity in its particular frequency range, which results in excellent bearing accuracy. The manual antenna frequency ranges overlap by about 20%, which can be very useful in practical situations.
Automatic DF-Antennas
- 10 MHz to 8 GHz
- High DF accuracy
- High immunity to reflections
- Fast bearings possible on signals of as low as 2.5 ms duration, which corresponds to two bearing cycles
- Built-in omnidirectional reference antenna
Applications
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.
The SignalShark combined with an ADFA is a high-performance and cost-effective solution for many applications such as:
- PMR and mobile network maintenance through fast, reliable localization of transmitters and interferers
- Frequency band management
- Monitoring communications at borders
- Protecting areas and signal reconnaissance
Situational Awareness of the RF Spectrum during DF
A central monopole is used as a reference element for DF and as an omnidirectional monitoring antenna. This allows the signals around the signal of interest to be monitored during direction finding by using a Spectrum View.
Azimuth and Elevation Data for Highend DF Performance
The bearing results of the ADFA contains azimuth and elevation information. This greatly improves the localization of transmitters that are not in the same plane as the antenna itself.
Bearing of Very Short Duration Signals
The ADFA works very quickly, taking as little as 1.2 ms for one bearing. This ensures reliable results, even for very short duration or pulsed signals such as push-to-talk (PTT), telemetry and hopping signals
Integrated Electronic Compass and GNSS Receiver
The ADFA is provided with an electronic compass and a GNSS receiver module for quick and easy alignment.
Fast and Easy Setup
No additional laptop needed
Simply connect the ADFA to the SignalShark and start taking bearings. The ADFA is controlled and powered from the SignalShark, which also has an integrated localization algorithm together with Open Street Map based heatmap visualization.
Magnetic mount adapter for vehicle use
The optional magnetic mount adapter allows the ADFA to be quickly mounted on the steel roof of a vehicle without the need for tools or fixings.
