  • Locking, adjustable waveguide shorting piston
    Patent number: 4688008
    Abstract: A waveguide shorting device having a shorting block and a wedge is disclosed. The shorting block contains a channel which is tapered so that it matches a taper of the wedge. A screw extends through the shorting block and engages a threaded hole in the wedge. Tightening the screw causes the wedge to be received in the channel and the shorting block to expand. Expansion of the shorting block clamps the shorting piston in a locked position within a waveguide.
