Adjustable Loads

These Adjustable Loads consist of a flanged section of straight waveguide containing a geometrically optimized absorbing element driven by a precision micrometer. There is more than one half wavelength of travel at the lowest frequency of each waveguide size. The micrometers used on these loads utilize a special dampening feature making the locking type of micrometer unnecessary. Our Adjustable Loads are available in sizes WR3 to WR42.

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

Ordering Example:

AL28S is an adjustable load in WR28 with Square flange. AL22R is an adjustable load in WR22 with Round flange.
