HEMP SHIELDED TRAILERS

MIT Antenna Trailers (Catalog #03000-019) MIT Lincoln Labs, Lexington, MA; 4/08-11/08

The antenna trailer is a reproduction of the trailers that accompanied the MIT ACF-IC2 Shelter. Each trailer contains a GFE furnished antenna, raydome, and shielded equipment bay that is integrated on a trailer that can be towed separately. Design and fabrication methods are employed throughout the contract to maintain an excellent degree of shielding against the effects of electromagnetic pulses and to control RF emissions.

ACS (Catalog #03000-018) Contract: TMC Design, Las Cruces, NM; 10/07-4/08

The ACS is a 16-foot long EMI/RFI shielded shelter similar to the MCATSII; it also serves as a frequency monitoring support van. The shelter is mounted on a EMI procured 25,500 lb. GVWR vehicle. EMI-RFI shielding is provided via a two-step design. The exterior aluminum skin is riveted to aluminum hat posts. This exterior skin provides a degree of shielding, but the bulk of shielding is provided by an interior 1/8-inch thick aluminum skin with fully welded seams. Wiring and conduit are surface mounted to protect shielding integrity. A personnel door and I/O patch panels are both shielded. COTS honeycomb air filter and AC and DC power filters are installed, as well as phone filter and single fiber waveguide for network connections. Two 5-ton air conditioners with hot gas bypass and 9 KW heat strips provide environmental conditioning. A pullout platform and step assembly is mounted under the personnel door. Belly box storage, cable reel, and spare tire carrier are installed underneath the shelter. Antenna mounting plates and interior unistrut strips for equipment mounting are installed. The interior of the shelter is finished with carpeting on the walls and rubberized safety tile on the floor. The ceiling is a drop down style with recessed fluorescent lighting. Furnishings include a writing board, microwave, water cooler, refrigerator, storage cabinets, and a GSA approved safe. Extra lighting is supplied by lamps mounted on the front of the equipment racks. Safety equipment is installed.

Radio Spectrum Measurement System Van (Catalog #03000-009) Contract: National Telecommunications and Information Administration (NTIA) Boulder, CO; 4/02-4/03

The Mobile RSMS Van is a 16-foot long EMI/RFI shielded shelter, and serves as a radio spectrum measurement support van. The shelter is mounted on a customer-furnished 25,500 lb. GVWR vehicle. EMI-RFI shielding is provided via a two-step design. The exterior aluminum skin is riveted to aluminum hat posts. This exterior skin provides a degree of shielding, but the bulk of shielding is provided by an interior 1/8-inch thick aluminum skin with fully welded seams. Wiring and conduit are surface mounted to protect shielding integrity. A personnel door and emergency escape hatch are both shielded. COTS honeycomb air filter and AC and DC power filters are installed, as well as phone filter and single fiber waveguide for network connections.
Three telescoping, rotating, antenna masts are installed. Compressor for raising the masts is installed on the front platform. A 36,000 BTU air conditioner with hot gas bypass and 5 KW heat strip provides environmental conditioning. A 20KW generator and manual transfer switch are housed in a compartment located within the confines of the shelter interior, but opening to the exterior for ventilation and maintenance. A pullout platform and step assembly is mounted under the rear platform and personnel door. Belly box storage, cable reel, and spare tire carrier are installed underneath the shelter. Antenna mounting plates, unistrut strips for equipment mounting, and a small removable winch are installed on the roof. Exterior lighting is supplied by two halogen fixtures. The interior of the shelter is finished with carpeting on the walls and ceiling and rubberized safety tile on the floor. Furnishings include wood storage units and work desk with bookcase unit. Radio equipment and UPS units are housed in three slide-mounted equipment racks with storage drawers, writing surface, and power strips front and rear. Operator chairs are provided. Customer-furnished safe is installed. Interior lighting is supplied by one overhead and one wall mounted fluorescent fixture, three DC powered dome lights, and ceiling-mounted track lighting in front of the equipment racks.

Spectrum Measurement Interference Control (SMIC) (Catalog #03000-006) Contract: Edwards Air Force Base, CA; 10/95 - 8/96

Edwards AFB contracted with EMI to provide three 14-foot EMI/RFI shielded, removable equipment shelters. EMI purchased the vehicles with ambulance and 4-wheel drive options, and completely constructed the equipment shelters. A rear storage area contains air conditioner, generator, pneumatic mast, and storage for ancillary equipment, and a front laboratory area contains equipment racks with work tops. Electronic equipment is installed by the customer.

NR Shielded Room (Catalog #03000-007) Contract: White Sands Missile Range, NM; 9/94 - 5/95

The requirement was to build an 11' x 16' x 10' shielded room rated to 100 dB from 100 KHz to 1.8 GH per MIL-STD-285. The shielded room was fabricated of 12 gauge galvannealed steel with fully welded seams. The walls and ceiling are fully insulated, covered with plywood and finished with carpeting. EMI used an RFI single knife-edged shielded door, RFI power filters and wave-guide-beyond-cutoff air vents to meeting sheilding requirements.
