you mean like anti-radiation drone? because in order to find direction of that signal you need relatively large (for physics reasons) and complicated (for practical reasons) antenna array. HARM has 25cm in diameter and is suited primarily for frequencies much higher than these used there. (higher frequency = shorter wavelength = all systems needed are smaller). here we'd need something 2x to 4x as big

also these particular jammers fuck up only 70cm band (handheld radio) and 900MHz band (used by some long-range drones), not even trying to jam normal fpv drones
