RCJ1390LT-I – Convoy Jammer

RCJ1390LT-I – Convoy Jammer


The convoy jammer RCJ1390LT-I is a vehicle mounted very high power jammer designed for blocking remote controlled improvised explosive devices Used by terrorist.
The RCJ1390LT-I is using state-of-the art technology for maximum performance and jamming the signals transmits to activate bombs.
The unit controlled by Microprocessor for PLL programming and use unique modulation technique based on mixed signal for maximum jamming efficiency.
Each module of RCJ1390LT-I transmits unique noise signal, which create “firewall” between the transmitter and its receiver.
The jamming signal is being generated by Multi-VCO chain which results very high sweeping rate along the bands hence create high RF density in each part of protected frequency band.
Jamming radius of RCJ1390LT-I depends on several conditions such as transmitter frequency and output power, distance to receiver and obstacles between.
System modularity allows flexible usage in different applications.
The system use Broadband Omni-Directional antennas for 360º protection.


  • Special Military Units
  • Special Police Units
  • VIP Protection
  • Bomb Disposal
  • Convoy Protection etc.


3 modes of operation:

1. Sweep/Barrage Mode
Jamming the whole frequency band at an ultra-fast Speed continuous sweeping.

2. Spot Mode
Jamming 4 frequencies from list of 10 pre-programmed.

3. Open Communication Window
Allows open communication from 6 pre-programmed options. Thus frequencies can be changed in factory when customer needs.


  • Designed to block wireless communication including HF, VHF, UHF, SHF, Cellular Networks, Satellite Phones, GPS etc.
  • Modules of Jammer operated separately
  • Separate switch ON/OFF and switch Operation Modes control for each frequency band.
  • Control output power for cellular bands from 5W up to 200W
  • External antennas
  • Remote control
  • Specific signal source per band for maximum jamming
  • Remote start of the system from a distance of 50 meters
