The "D" Series is a range of portable jamming systems designed for fast deployment in ruggedized briefcase form. 
Applications
- RF Communication Jamming;
- Remote Carry Forward Role, Event, Base or Venue Protection;
- EOD Render-Safe Procedures;
- VIP Protection.
The "D" Series jamming system has been designed to provide an efficient and effective jamming system in a small, highly ruggedized package. The "D" Series extends the range into UHF, Satellite Phone, 3G and WLAN Bands, as well as providing many new features.
The "D" Series is a single unit to cover both GSM900 and GSM1800 bands (D9). This single system can be easily transported to site, switched on and pointed for instantaneous jamming of required bands.
Area of coverage is dependant upon factors such as distance from the cell nodes and proximity of local infrastructure, but coverage of several KM can be obtained. A low power switch is available to attenuate the output signal and conserve battery power.
The "D" Series also has the facility to add in omni-directional antennas for instances where the target location is not known. "D" systems are available with on board batteries supporting autonomous operations for up to 4 hours.
Multiple frequency bands provide:
- UHF (D7);
- GSM (D9+);
- 3G (D10);
- WLAN 2.4G (D11);
- WLAN 5.5 G (D12)
- Satellite Phone (D14).
Options also include hard wired and wireless remote control. All "D" Series equipment can be powered from 15 to 30 VDC for continuous field operation and comes with 85-264 VAC charger unit to recharge the battery system with a visual alarm when the battery is low.
