This water load has the Varian grooved flange and a -60 db E-field probe.  As in the R284-3.0, this high power load is very useful for converting a circulator into an isolator.  The broad band performance of the load is especially useful for magnetron applications because it absorbs the spurious signals, as well as the desired fundamental, with equal efficiency.

It is an extremely broadband water load that covers almost the entire bandwidth of the WR284 waveguide.
