Attenuation @ 1000 MHz
0.250" Semi-Flexible coaxial cable is a formable, microwave grade with mode free operation to 19 GHz. The tin-soaked copper braid provides near 100% RF shielding and the malleable nature of the outer jacket eliminates solder joint failures and allows bends immediately behind the fillet. Standard 0.250" SF cables do not have a jacket/sheath, but most manufacturers provide a jacketed variation identifiable by its bright blue jacket.
Semi-flex cables are dimensionally and electrically similar to their semi-rigid counterparts and have a tinned-copper-braid outer shielding that provides RF shielding greater than 100 dB. The hand-formable cable assemblies do not require special tooling to shape or reshape the assemblies and can be formed more than once without damaging the outer conductor.
