Since 1987 ATEC Industries has
been continuously involved in the design, fabrication, construction
and testing of Radio Frequency (RF) shielded facilities. ATEC
specializes in Electromagnetic/Radio Frequency Interference
shielding (EMI/RFI) for governmental, military and medical
facilities, both as stand-alone projects and as part of larger
integrated construction projects.
ATEC’s extensive list of successfully completed projects
includes millions of square feet of RF shielding in the United
States and overseas. These projects have included:
One-inch thick welded steel plate
Copper soldered shields
Combination SCIF/RF facilities
RF modular enclosures
Welded aluminum enclosures
ATEC has successfully completed every project to date without
exception. RF attenuation requirements have varied in the
magnetic and electric (H&E) fields from 50db at 1KHz to
100db at 100KHz to 100db at 50 MHz and microwave performance
of 115db at 18 GHz to 80 db at 50GHz.
Our engineering and project management teams enjoy decades
of experience, not only in the intricacies of RF shielding,
but also in the integration of the shielding into the parent
facility and the coordination of the trades that are critical
to this type of project. ATEC’s early involvement in
the design and construction process helps us to ensure that
the most appropriate RF engineering solutions are applied
to your project. ATEC’s project management and field
supervisory personnel will eliminate costly mistakes and the
schedule delays that inherently follow.
Whatever your RF shielding requirement, ATEC has the expertise
and commitment to provide you with a facility that will meet
your needs today and for years to come.
Recently completed projects include:
Ground Based Midcourse Ballistic Missile Defense System
Ft. Greely, Alaska
Six HEMP shielded facilities, including two at a remote island
in the Bering Sea. The total square footage was in excess
of 85,000 SF and included 24 HEMP doors, 89 RF electrical
filter cabinet assemblies with MOVs, multiple waveguide penetrations,
Pulse Current Injection Testing, RF Attenuation and SELDS
testing. Completed 2004.
Advanced System Integration Laboratory
Naval Air Warfare Center
Patuxent River Naval Air Station, Maryland
Design/build with local General Contractor to construct an
RF shielded aircraft hangar with Radar Absorbing Material
(RAM). Interior self-supporting RF shield was 195’x180’x90’H
and included a rolling RF Shielded Anechoic Door, 165’x75’H,
which weighed over 400.000 lbs and was sealed by a series
of pneumatic bladders with beryllium copper mating surfaces.
The entire RF facility was certified for RF attenuation in
excess of 100 db to 18 GHz. Completed 1999.
Naval Facilities Engineering Command
Installation of over 75,000 SF of #430 stainless steel HEMP
shielding that enveloped two communications buildings. The
completed facility is certified in accordance with Mil Std
188-125-1. Components included four interlocked vestibules
with 12 semi-automatic RF shielded doors, over 400 SF of waveguide
array tube assemblies, and 13 inductive element HEMP filter
cabinets with MOVs. Completed 2000.
