The Estonian electronic and defense industry company Rantelon is launching a fourth-generation portable solution for countering drones, designed to address the rapidly changing threat of unmanned aerial vehicles in law enforcement, internal security agencies, and the protection of critical infrastructure.
The new device allows for the neutralization of not only drones controlled on conventional frequencies but also low-frequency unmanned aerial vehicles, the use of which is rapidly increasing in modern conflicts.
"The threat from drones is changing very quickly, and countermeasures must keep pace with it. In developing the new device, we focused on covering important frequency ranges while also making it intuitive to use and reliable," said Rantelon CEO Karl Taklaya.
The new model of the anti-drone gun, PJ-4058, reflects the rapid development of the Estonian defense industry in a field where technological needs change within months. The device was developed in collaboration with practical specialists and draws on nearly 30 years of Rantelon's experience in developing radio frequency systems and the expert knowledge in counter-drone technology accumulated over the last decade. It can be used, for example, by police and border guard operations, in the defense sector, as well as during large events or near critical infrastructure facilities, where it is necessary to protect people, airspace, and strategic objects from the threat of drones.
From a technical standpoint, the device is designed to suppress drones on both conventional and lower control frequencies. "This is an increasingly important capability, as, for example, the use of FPV drones operating on lower control signals has significantly increased on the battlefield in Ukraine," explained Taklaya. The flexible design of the device allows for frequency modules to be replaced if necessary, enabling the potential for counter-drone capabilities to be updated without replacing the entire system.
The anti-drone device is equipped with special protection against wave reflection (VSWR), which helps prevent damage to the instrument and maintains its reliability even if the antenna sustains physical damage. Rantelon's engineers also paid great attention to signal purity, ensuring that the generated interference remains within the allowed frequency band and does not affect external frequencies.
Previous-generation counter-drone devices from Rantelon have undergone international testing, and their capabilities have been verified in real combat conditions in the Middle East and Ukraine.
Rantelon is a high-tech Estonian company founded in 1995 that develops and manufactures radio frequency electronic equipment and systems. The company's product portfolio includes solutions for detecting and suppressing drones, electronic warfare systems, and other radio frequency technology-based solutions used both in Estonia and in foreign markets.
