OVERVIEW: C-UAV Directional Communications Jammers are specialized electronic warfare systems designed to disrupt the command, control, and navigation links of hostile drones. Using focused high-gain antennas, they target both RF control and GNSS signals to neutralize UAV threats with minimal collateral interference.

GENERAL DESCRIPTION: These jammers use directional antenna arrays or AESA technology to emit high-power, narrow-beam jamming signals toward targeted UAVs. The system typically covers commercial RF bands (e.g., 2.4 GHz, 5.8 GHz) used for drone control and telemetry, as well as GNSS bands (such as GPS L1/L2, GLONASS, BeiDou, or Galileo) to disable satellite-based navigation. By focusing the jamming energy, the system can extend effective range and reduce unintentional disruption to friendly assets. Modern C-UAV jammers are portable or vehicle-mounted and often form part of a layered defense system including radar, EO/IR tracking, and kinetic effectors.
