An electronic warfare version equipped with Grinaker systems Technologies (GST) and GSY 1501 jamming systems is one variant of the helicopter. The EW platform can interrupt communication during air, land and sea battles. Another variant of the Oryx featured dome shaped antennas which were substituted for the main cabin door.

The system provides full COMINT/EW capability from detection and interception, through direction finding and recording, to disruption by deception or jamming. It covers the frequency spectrum from 20-1000Mhz, with optional extension to 1.45Mhz,and can be used against voice and data links. DSP techniques are used to perform noise-riding signal detection for rapid scanning with a high probability of detection.

Handled 501. I've used some of the values for COMINT from the other source you indicated which was a bit more explicit as to the system used on the Oryxes: https://dziennikzbrojny.pl/artykuly/art,6,27,1658,lotnictwo,smiglowce,od-pumy-do-caracala-czi-a
