REBUS with RF Enclosure

• A REBUS Jammer connected to an RF screened self-erecting enclosure that covers most luggage, for use in Airports and other mass-transit locations or crowded places
• Block the trigger signal to a radio controlled improvised explosive device without touching it
• Bridge the gap between a First Response and arrival of the Bomb Disposal Team
• Maintain radio communications between response teams in and around the safety cordon
• Preserve operation of public cell phone networks

NSN No: 5865-99-346-4625

The REBUS jammer system is a low power RF inhibitor connected to an antenna in an RF shielded enclosure

The inhibition is contained underneath the enclosure and focussed exclusively against the RCIED. The power of the REBUS jammer is held under the enclosure by a layer of electromagnetic screening fabric. This shield contains the inhibition, so that all the power is employed against defeating the power of the remote transmission signal used to initiate the radio controlled improvised explosive device (RCIED)

Stops RCIED receiving a trigger signal. The inhibitor jams the reception of a trigger signal by the (RCIED). The RF shielding of the enclosure also blocks and filters the incoming trigger signal.

Allows security teams to use their radio communications close by. Communications devices used by the Response teams working in and around the safety cordon are not affected by the inhibitor even when they are in close proximity. The electromagnetic screening material in the enclosure is a two-way barrier, filtering incoming signals and containing the electronic counter measures (ECM) signal under the enclosure.

Does not interfere with critical radio communications like airbands. The range of the REBUS jammer is limited to the area under the enclosure so it does not affect any other radio signals in any part of the radio spectrum.

No need to shut down cell phone networks. There is no need to shut down a cellphone network because the REBUS jammer system prevents just one pair of cellphones from connecting (the transmitter used by the terrorist to activate the IED and the receiver which is part of the IED).

The REBUS low power RF inhibitor:

Overcomes all threats in a single box. The inhibitor simultaneously covers all threats in the frequency range 20MHz – 2.4GHz including GSM and 3G mobile phones, popular VHF PMRs and UHF PMRs (hand-held radios and walkietalkies), and Wi-Fi. No programming or training required

Low power efficiency. Because it is in position right next to the device, the inhibitor only needs a low power signal source to overpower a much stronger trigger signal transmitted from a distance. In tests, the inhibitor repeatedly killed high-power PMR signals at unrealistically close proximity.

Simple to use. The inhibitor is very simple to operate and its status can be observed from a distance.

ECM time delay start. The inhibitor slowly increases the RF power over a 60 second period, giving the operator time to walk away from the device in safety.

Up to 8 hours run time. The inhibitor’s internal rechargeable batteries will run for 4+ hours, and can be supplemented by an external battery pack to provide a further 4+ hours of run time.

The RF Enclosure:

Covers suspect bags without making contact. The enclosure is flexible and lightweight. It is quick to deploy and connect to the inhibitor. The enclosure covers bags up to 77cm x 60cm x 28cm (30” x 24” x 11”) so is ideal for use in airports,
train stations, metro systems and crowded places.

Normal EOD SOPs apply. A bomb disposal team arriving on scene has the immediate assurance that any potential radio controlled improvised explosive device (RCIED) has been safely isolated.

Visual inspection can be made through the disruptor access port using a torch.The nature of the suspect device can be verified by X-ray directly through the walls of the enclosure.

A disruptor can then be precisely aligned and fired through the disruptor access port to target the device inside. The “sock” within the access port is made of flexible electromagnetic screening fabric to maintain the integrity of the RF protection when the port is open.

NOTE – The RF Enclosure offers NO blast protection.
