PELENA-7M-4

COBRA

Purpose
The device is designed to protect against unauthorized eavesdropping using special radio devices and prevent the detonation of radio-controlled explosive devices (RCIEDs). It is used in situations requiring high-power signal suppression across a broad frequency range - from basic civilian radio devices (alarms, walkie-talkies, etc.) to Wi-Fi data transmission systems - while providing enhanced protection in cellular frequency bands.
Key Features

Provides effective suppression of high-power signals
Fully covers a wide frequency range (20-6000 MHz) without any gaps
Features reinforced cellular device jamming capability. Operation modes are controlled via front panel toggle switches
Delivers optimized suppression of GSM 900/1800 and 3G standards through specialized jamming signal modulation tailored to specific cellular standards
Maximizes suppression of common civilian radio devices operating at 433 MHz (e.g., car alarms)
Includes remote control for enhanced operational convenience

Power Supply
Powered by vehicle electrical system (13.8 ± 1.2) V
Package Contents
Main transmitter unit, three additional magnetic-mounted transmitter modules, set of magnetic-mounted antennas, remote control, installation and spare parts kit, vehicle power cables, operation documentation.
