| Max range | 25 km |
| Guidance | None needed: area-denial barrage jamming of satellite navigation, not target-specific |
| Bands | GNSS bands of GPS, GLONASS, Galileo and BeiDou |
| Endurance | Fixed, mains-powered installation (continuous duty) |
| Mount | cell tower / mast |
Each R-340RP antenna is credited with at least 25 km in a 125 degree sector, and 100 antennas with a 150 x 150 km zone; these come from Russian media (TopWar) via Defence Redefined. Deagel gives 80 km per module and 50 km for Polye-21M, so range figures vary widely. In service since 2016. The Armenian combat claim (four days of effect against Bayraktar TB2) is unverified.
