The Flann Series 540 Terminations consist of a length of uniformly sized waveguide.

Within the waveguide is a close fit sliding load which moves in a precisely controlled manner. It is desirable to use a sliding termination when measuring low VSWR values.

The effect of sliding the termination enables the user to deduce low VSWR values to a greater accuracy than that achieved by a fixed termination technique.


  • Low Housing VSWR
  • Low Sliding Element VSWR
  • Models from 1.14 GHz to 140 GHz
