The BNT-S900-B8 Backpack Starlink jammer delivers multi-band disruption with 50W per channel, covering S, C, Ku & GNSS. Battery lasts 60-90 min. Ideal for tactical use.
When a fixed installation simply isn’t an option, the BNT-S900-B8 Backpack Starlink jammer fills the gap. Weighing roughly 16 kg without antennas and housed in a custom ergonomic pack, it gives rapid-response teams a true grab-and-go capability. Instead of relying on vehicle-mounted racks, one operator can carry full multi-band denial power into remote border zones, temporary checkpoints, or any environment where Starlink terminals need to be silenced fast.
This system isn’t a stripped-down handheld. It packs eight independent 50 W channels driven by a software-defined radio exciter. The integrated 29.4 V / 30 Ah Li-ion battery sustains 60 to 90 minutes of continuous output before a recharge is needed, and active cooling with high-speed fans keeps the unit stable under full load. Because the whole build sits in a compact 488 × 369 × 189 mm frame, mission planners gain a tactical Backpack Starlink jammer that doesn’t sacrifice raw power for portability.
Quick-release buckles and padded straps make donning the pack intuitive, even with body armor.
An external controller lets the operator select bands, adjust output, or kill transmission instantly without opening the pack.
Hot-swap-capable battery architecture (optional accessory) can extend field time beyond the stock 90-minute window.
At the heart of the platform is a wideband SDR that generates precisely shaped interference waveforms. It receives target bearing data from companion detection-and-location sensors, then locks the disruption beam on the threat terminal. Against Starlink downlinks typically arriving at -60 to -80 dBm, the Backpack Starlink jammer injects enough noise to exceed the signal level at the receiver, severing the satellite link. Thanks to high-gain directional antennas that remain compact, a 5 km stand-off range is easily achieved while keeping the system easy to maneuver.
For operators who need omnidirectional saturation, the included full-band whip antennas flood the immediate 1–1,500 m isolation zone. Both modes can be active simultaneously, giving field commanders the flexibility to shape the denied area on the fly.
| Frequency Band | Uplink / Downlink Range | RF Output |
|---|---|---|
| S-Band (Low) | 1980 – 2010 MHz | 50 W |
| S-Band (High) | 2170 – 2200 MHz | 50 W |
| C-Band (Low) | 3700 – 4200 MHz | 50 W |
| C-Band (High) | 5925 – 6425 MHz | 50 W |
| Ku-Band (Low) | 10700 – 11450 MHz | 50 W |
| Ku-Band (Mid) | 11450 – 12100 MHz | 50 W |
| Ku-Band (High) | 12100 – 12750 MHz | 50 W |
| GNSS L1/L2 | 1170 – 1280 MHz | 50 W |
| GNSS L5 | 1550 – 1620 MHz | 50 W |

Note: Performance figures assume line-of-sight conditions. Dense urban clutter may reduce effective range. For a deeper look at satellite terminal vulnerabilities, refer to the Kratos defense brief on tactical jamming.
Maneuver Warfare: Squads can deny adversary C2 links during assault or retrograde operations, eroding the enemy’s ability to coordinate via LEO constellations.
Critical Infrastructure Protection: Deploy around power plants, border fences, or government compounds to block unauthorized surveillance feeds or remote-triggered threats.
Spectrum Policing: Regulatory teams use the integrated direction-finding interface to identify rogue Starlink terminals and apply precisely timed bursts, keeping the electromagnetic environment orderly without excessive collateral interference.
If your mission set also covers counter-UAS operations, have a look at our portable drone jammer lineup (internal link). Pairing the two platforms creates an integrated C-UAS and counter-satcom bubble that moves with your team.
