Definitely not the best setup, but enough to show me that this thing covers the upper edge of the 10GHz hamband well.
10.368GHz was a bit in the slope.
@ftg at 100ghz, 3mm, is that acting as a dummy load, or a polarizer/grating?
@lizakowski
As a stand so that it's not on desk level.
That's more or less it
@ftg oh, I thought there was an open waveguide resting on the fins 
@lizakowski
Yeah that's understandable.
The filter is this style and the inside dimensions are approximately WR-75 sized.
