A test box or bag using the Faraday Cage principle allows distress transmitters to be tested without radiating a signal likely to cause a false alert.

Elimination of ambient radar signals also allows SARTs to be tested for correct "standby" operation.

The box, model FC2, is seam-welded aluminium, lined with broadband microwave absorbent foam to cut down internal reflection. This prevents abnormal loading of the transmitter under test, and allows a clean signal to be passed to external test equipment. The lid is hinged and self-supporting, and is sealed with Copper/Beryllium finger strips.

The bag, QRT-101, is manufactured from nylon cordura coated with polyurethane. The inner layers are two sheets of copper-nickle on polyester substrate. All seams are double folded for strength and prevention of signal leakage. The enclosure is water resistant, will float, is non-corrosive and is modular for ease of repair or replacement of components.

A sniffer antenna is connected to a BNC connector to allow connection to the tester directly or through an attenuator.

The FC2 can accommodate all but the largest current beacon types whilst fitting in the trunk of a car. The bag QRT-101 is collapsible for ease of storage and transportation.
