ukraine has to invent new ew systems every month  the times. ukraine has to create new solutions within just a few weeks to effectively counter russia's changing weapons.  one of the new products is a ground robot equipped with special antennas capable of blocking drone signals within a radius of up to 300 meters. this robot can not only neutralize drones, but can also be used to evacuate the wounded from the battlefield. antennas create a "dome" defense, blocking radio signals, and in the case of directional action, can disable the drone at a distance of up to 10 kilometers.  another development is "hedgehog" type backpacks equipped with a large number of antennas operating in different frequency bands and allowing to jam drones. these devices provide protection up to several kilometers away and cost about $6,000 per unit. these innovations are designed to save the lives of defenders on the front lines. "if you're on the frontline without this equipment, you're unlikely to live longer than an hour," serhii skoryk, commercial director of kvertus. such innovations allow the ukrainian army to effectively combat drones, maintaining a vital advantage in the face of constant competition with russian forces. source:   d5-7307-46b5-b0f0-1c810f388d73   s/1848259301317722503
