The Pole-21 radio jamming module is an important part of the Russian military’s radar network, electronic warfare equipment, and multi-layered air defense system.
The Pole-21 complex is developed by the Scientific and Technical Center of Electronic Warfare (STC EW), based in Voronezh and St. Petersburg, Russia developed. Currently, the modernized version Pole-21M serves in the Russian Army and the export version Pole-21E is being promoted on the international market.

Pole-21 is designed to counter enemy high-precision weapons and other weapon systems that use satellite radio navigation systems by jamming and disabling transmission signals.
Regarding components, Pole-21 is designed based on modular principles, which simplifies production, deployment and reduces costs. Each Pole-21 complex includes from 1 to 3 jamming modules (up to 100 antenna posts), R-340RP radio stations can be placed on the jamming tower at a suitable height, on truck chassis or existing cell phone towers.
Each antenna module is capable of suppressing radio signals at a range of about 25km. Each antenna pillar has a capacity of about 600W. Communications between the components of the Pole-21 complex can be maintained throughout via radio waves or wired transmission systems. Therefore, during the installation of stations on mobile towers, the GSM antenna can be used as a backup option.
Regarding combat range, Pole-21 can be deployed and installed in large numbers and over a large area, depending on the terrain. Under favorable conditions, each Pole-21 complex can create an “invisible dome” covering an area of up to 150km2, deflecting or disabling global satellite positioning signals in the area. frequency 1176.45-1575.42 MHz.
