1. An elongate flexible waveguide section for radio frequency signals, wherein:
the waveguide section has a first series of corrugations in a longitudinal direction; and
the waveguide section has a second series of corrugations in at least a portion of a circumferential direction perpendicular to the longitudinal direction;
wherein the amplitude of the second series of corrugations is modulated by an amplitude of the first series of corrugations.
