Several
types of the Broadshield counter-IED jammers are available from
the UK based TRL company, a member of the L3 Communications
group. Broadshield is offered in vehicular version and in a
two-set man-portable system, addressing different waveforms
and frequency ranges.
In the man pack role the battery powered system transmits 10
watts of power, with continuous frequency coverag, and
selected banded coverage, addressing
wireless communications bands such as GSM.
The system is mounted in a backpack with the antennas and control
panel accessible on the top face, and a long mission-life Lithium
Ion battery mounted below. The system weighs 15 lbs, with batteries,
antennae and backpack. The unit can be synchronized to support
interoperability with other ESM/ECM and communications equipment.
Once programmed by a mission specialist, the system runs automatically
from switch-on. Future models of the system, currently in development
will extend frequency coverage of the BroadShield in a single unit, fully integrated with a signal generator
and power amplification components.
