1-7. Equipment Characteristics, Capabilities and Features. The S-280B/G and S-280B/G
Shielded shelters are lightweight, relocatable shelters used to transport and house ground communications
equipment. The foam and beam shelter construction consists of aluminum face sheets enclosing a polyurethane
foam composition core. The shielded shelters are equipped with radio frequency/electromagnetic interference
(RFI/EMI) shielding to protect the electronic equipment contained inside. The shield is a continuous metallic
surface which includes the shelter panel inner face sheets and conductive materials which maintain continuity
around joints, door openings and other possible sources of radiation leakage. Shielded shelters also have an
RFI/EMI filter inside the emergency exit panel. Shielded shelters can be identified by the metallic door gasket
which mates with another conductive surface on the doorjamb. The shelter is designed for outdoor use in all
weather conditions.
