0.141" Semi-Flexible coaxial cable is hand-formable and microwave grade with mode free operation to 34 GHz. The cable's easy forming, excellent shielding, and very low PIM makes it a popular choice for use in component interconnection.

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 0.141" SF cables do not have a jacket/sheath, but most manufacturers provide a jacketed variation identifiable by its bright blue jacket. It's availability in multiple colours makes for easy identification of separate radio chains.
