AT-619 Portable FPV Countermeasure Shield
The AT-619 portable FPV countermeasure shield is built on SDR signal interference technology and supports multiple
band configurations. It effectively jams drone data/video links, remote-control links, and navigation signals, with
especially strong performance against various DIY FPV drones.
Compact and easy to carry, the device uses a shield-style form factor for high concealment. With an IP54-rated,
highly durable housing that is heat- and corrosion-resistant, it can be rapidly deployed for squad-level defense,
counter-terrorism tasks, event security, and protection of military and police facilities, while maintaining a low
visual profile and avoiding panic.
Key features
- Portable and discreet: Compact structure with a shield-style design, easy to carry and highly
concealable, reducing the risk of causing public alarm during use. - Effective FPV countermeasures: Digital-modulation jamming source efficiently blocks FPV
remote-control signals and disrupts hostile FPV attacks. - Flexible configuration: Two band configurations available (FPV-only or FPV + conventional UAV),
allowing precise alignment with different mission profiles. - Sustained effectiveness: SDR architecture supports algorithm upgrades, ensuring long-term
effectiveness and adaptability against new drone models and protocols.
