Ultralight field drone jammers for infantry 🎇

From a perspective of drone pilot, it is crucial to have video from drone camera or to track the drone position via GPS. Pilots usually depend on both features to accomplish missions successfully. Since the drone is always out of pilots site in real life situation, it is useless without FPV and GPS position and navigation. No AI can help it. No visible targets, no GPS tagging of targets or targeting, no video of terrain.....no drone treat to you.

With these parameters in mind Jammers4u has created a new generation of drone jammers that focus on video streaming and GPS signals. That has enabled us to make a highly effective drone jammer with more range, power and portability in comparison to conventional jammers with similar effect on drones.
New generation of drone jammers ignores control frequencies, vigorously focuses on video and GPS signals, and effectively renders the drone blind and disoriented, thus useless in combat situation. Extra range comes handy for disabling reconnaissance drones, since they do not come too close. Making enemy drones blind and disoriented will give troops a chance to safely maneuver.

It has became a necessity to protect infantry groups from lethal artillery guided by live video feeds from reconnaissance drones. Target that has been GPS tagged is usually sentenced to death. We have had soldiers on terrain in mind when we designed these light and simple models.
