Belden makes a hand formable flexible version of semi-rigid cable called Conformable® Coax. Belden Part numbers 1671A (RG0495/U Type), 1672A( 75 ohm, .087"), 1673A (RG-402/U Type), and 1674A (M17/151 Type). These are lower cost alternatives to semi-rigid, eliminating the need for special tools and drawings for assemblies. Ideal for breadboarding, prototyping, and possible production substitution, the cables use standard SMA connectors.
