A supporting system for a delay line of a travelling wave tube wherein a number of clamping rings press dielectric support rods against the delay line. The clamping rings have a natural length along the delay line and a spacing distance such that (Nxw lambda )/4=L1,2, where L1,2 designates the length of the line resonators, lambda w the wave length on the delay line, and N a whole uneven number.
