SB (Strip Band) Coaxial Cables
Coaxial and Data Cables
SB coaxial cables have been designed for low attenuation at high frequencies, while using similar dimensions to MIL-C-17 constructions. Standard connectors may frequently be used, thereby avoiding tooling charges.
Solid PTFE dielectrics are manufactured with tight tolerances to ensure impedance uniformity and to effect VSWR levels that meet or exceed MIL-C-17 specifications for cables of comparable size. The strip braid configuration is by far the most effective means of lowering attenuation levels of coaxial cable at high frequencies while providing shielding effectiveness levels that exceed those of flexible MIL-C-17 cables. Flat strips of silver plated copper are braided over the dielectric core, frequently with an intermediate metallized mylar or kapton layer, and an outer round wire braid. This shielding technique provides superior shielding effectiveness and lower transfer impedance than any standard double braided mil-spec construction.
FEP jackets are typically used, but alternate designs are available such as flame retardant PVC and abrasion resistant overall braids. Marker tapes or surface printing are used for positive identification.
