Rohde & Schwarz has unveiled a modular multi-band jammer for its Ardronis Effect counter-drone system, enhancing its ability to disrupt communications across a wide range of frequencies.
Previously, the system could only stop manually controlled drones via radio frequency, offering reactive and non-reactive jamming modes.
With the new multi-band jammer, Ardronis Effect can now disrupt multiple frequency bands simultaneously, including those that employ frequency hopping or use encrypted communication.
The upgrade also enables the system to use custom waveforms, adapting to the different communication methods employed by hostile drones.

The Ardronis Effect was built to minimize interference with nearby friendly signals and features an open architecture for easy integration into other counter-drone systems.
It comes with an early warning capability that detects radio signals from a hostile drone’s remote control, allowing disruption before the enemy launches it.
Jam All Frequencies
Jamming all potential frequencies, especially during drone swarm attacks, is crucial in modern warfare.
While the German-made multi-band jammer does that, the real challenge is jamming a wide area in a way that is effective enough to stop weaponized or intelligence-gathering drones.
“This requires ARDRONIS Effect to jam simultaneously on multiple bands at high output power across the entire spectrum without gaps in time and frequency,” noted Jan Link, the company’s Product Manager for C-UAS Solutions.
The Ardronis Effect is part of Rohde & Schwarz’s Ardronis family of counter-drone solutions, which also includes Ardronis Detect, Ardronis Locate Compact, and Ardronis Locate Advanced systems.
Each system is modular, allowing them to operate independently or together to meet specific mission requirements.
