Yes, drone jammer can counter drone attacks effectively, but its effectiveness depends on several key factors.
1. The drone jammer will overheat during long-time operation, making it impossible to work 24/7 without a cooling fan. For mobile deployoment, it's recommended to choose a jammer with a built-in battery for portable use.
2. Choosing the right frequency bands is essential. You have to have a jammer which at least will cover 800-900MHz, ideally 5.8/1.2 for video transmission and 2.4 GHz and 433 MHz for FPV (first-person view) control. Even so, FPV will go to failsafe and can hit the target if done smart.
3. It’s important to understand the operational environment. Drones has the ability to handle signal interference from Wi-Fi, Bluetooth, and other wireless systems, especially in urban areas. This means that low-level jamming is often insufficient to interrupt their mission.
To be effective, you have to overpower the transmitter signal to the drones. Your jamming strength falls off as 1/distance2 so your jammer can't be too far away.
If a drone is launched from as far as 2 kilometers away, and jamming coverage is not wide or strong enough, it’s likely to penetrate your defense. You're probably going to have a bad day, unless you have jammers everywhere.
Although directional jammers can focus energy to increase range, they require precise aiming and real-time tracking, especially against fast-moving or agile drones.
Pro Tip:
For higher effectiveness, drone jammers are often part of a multi-layered counter-drone system, combining detection (radar/RF sensors), tracking (EO/IR cameras), and neutralization (jammers, nets, lasers, etc.). And can cover a wide variety of frequencies and a long jamming range.
