Precision Tunable shorts are used to provide a variable short circuit reference plane in waveguide set-ups. Each of these tunable shorts consists of a flanged section of straight waveguide with a micrometer driven short attached to one end. The micrometer drive provides precise movement of the shorting plunger of more than one half wavelength at the lowest operating frequency of each waveguide size. The micrometers used on these shorts utilize a special dampening feature making the locking type of micrometer unnecessary.

This product is now available with a metric micrometer drive assembly.

Ordering Example: N-TS28R is a tunable short in WR28 with a round flange with a non-contacting short.
