System and method for suppressing radio frequency transmissions

A system for screening potentially hostile parties, the system comprising:

• a transmitter that concomitantly generates suppressing signals within two or more predetermined frequency bands that are discrete and separate from each other, the suppressing signals being broadcast from the transmitter to a volume of influence surrounding the antenna, the suppressing signals having the effect of suppressing radio frequency transmissions within a volume of influence surrounding the antenna;
• and
• a screening module that screens potentially hostile parties for explosives,
• wherein the transmitter and the screening module are arranged such that the screening module is positioned within the volume of influence during operation to inhibit an explosive device from being remotely detonated while the screening module is being used to search for explosives, and
• wherein the transmitter and the screening module are configured and operated such that the effectiveness of the transmitter is not substantially impeded by the screening module and the effectiveness of the screening module is not substantially impeded by the transmitter.
