The entire DF system comprises of fully integrated receivers, battery, charging unit and control circuitry in a compact sturdy carry case, ready for quick and easy deployment anywhere, with or without external power sources.

The fully weather-proof antenna system comes with a sturdy tripod and employs 8-pole arrays for HF/VHF and UHF frequency bands for maximum accuracy.

For maximum operator convenience, the bearings are indicated in numerical format, both as instantaneous and averaged values.

The circular azimuth display, with a freely adjustable North reference, has an additional “polar mode”. This allows the user to assess the signal strength relative to the trace length. An adjustable trace decay time can assist with recognising random reflections.

The waterfall and histogram graphics give an instant overview of the signal bearing distribution over time, assisting in validating the quality of the signal azimuth indicators.

The system can be specified with a single or dual receiver configuration. In a dual receiver setup it is possible to monitor the demodulated audio signal of the received frequency, without any interference, which is inherent to the pseudo-Doppler technique.

There is also a GPS option available, which permits the logging of the measured azimuth values in relation to their GPS coordinates. This allows for post-processing using GIS software packages, which in turn can assist in pin-pointing the signal location by using triangulation methods.
