Shielding
The graph below depicts a general comparative shielding effectiveness (attenuation in
dBs) of all three types of SHIELD-FLEX conduit. The dotted line indicates a comparison
to standard unshielded liquidtight flexible conduit Type LA. The spectrum of test
frequency is from 1 MHz to 10 MHz Electric Field, to 100 MHz to 1 GHz Planewave
Field and 2 GHz to 6 GHz Microwave Field. Tests were performed per MIL-STD-285 on
1" trade-sized conduit using standard liquidtight fittings from Thomas & Betts Series
5300. Results are based on controlled laboratory conditions and may vary in actual
field-installed conditions.
