This high power water 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.  Another option for your system may be the R284-3.0 Waterload with Integrated Tuner.
