Abstract: This technical disclosure is for a structurally self-contained, RF-shielded enclosure which is rapidly deployable due to it's ultra light weight and ease of assembly. Assembled by one person in one half hour, the enclosure becomes an RF-shielded, free standing room within an existing non-secure room or environment. Lightweight metallized fabric is sewn together with rugged tent fabric and ballistics cloth. Fiberglass rods are connected to aluminum sleeves and unions to configure the room. A bulkhead assembly penetrates the side wall and provides filtered power and electronic signal interfaces. Honeycomb air guides and an electric fan facilitate air exchange within the room.
