Attenuation is a measure of the ability of a component to carry an RF signal efficiently.

Coaxial cable loss is the sum of the dielectric and conductor losses and is a function of the materials used to manufacture the cable. Attenuation stability with flexure will have similar response characteristics as "Phase vs. Flexure" describes previously, as will the "tracking" characteristics. Attenuation matching will not be as dependent upon the dielectric style, although for long lengths the insertion loss stability vs. flexure is critical.
