2.5dBi Omni Antennas Handheld Digital Signal Jammer
This professional handheld digital signal jammer blocks GPS, Glonass, and 4G communications with 2.5dBi omni-directional antennas. The 6.5Watt device effectively disrupts communications between RF wireless equipment including mobile phones, cellular base stations, Wi-Fi networks, and satellite phones without interfering with other communication systems.
Product Overview
The U-JN8DGN model features 8 signal frequencies controlled by 4 antennas with individual DIP switch controls for each frequency channel. Utilizing advanced digital noise technology, this jammer delivers twice the jamming range compared to traditional VCO technology jammers.
Key Features
- Compact, portable design for easy carrying and deployment
- Multiple frequency bands with individual channel on/off selector switches
- Extended battery life exceeding 1.5 hours of continuous operation
- Digital signals modulated to VCO produce RF signals that resemble noise in the RF spectrum
- Eight RF frequencies controlled by four high-efficiency antennas
- UWB frequency matching technology reduces antenna quantity while enhancing working efficiency
- Advanced digital Gaussian white noise technology for superior interference performance
Important: Do not turn on device until antennas are properly fixed in place.
