Nylon cord performs excellently in thisrespect.

Radio dial cord, also known as tuning cord or string, is a component used in older radio sets to control the tuning mechanism. It consists of a thin, flexible string or cord that is connected to the tuning knob or dial, and is threaded through a series of pulleys and gears inside the radio\'s chassis.
When the tuning knob is turned, the dial cord rotates the tuning mechanism, which in turn adjusts the radio\'s frequency to the desired station. The tension of the cord is important for ensuring accurate tuning, and adjustments may need to be made over time as the cord stretches or wears.
