[NLRS] Short length of WR90 needed

[billd at 2z.net]

Hi Guys

  In the continuing effort to get 10Ghz on the tower, it looks like I MUST filter 
the 10Ghz "exciter" .... So in order to build the N6CA filter, I am looking for
5.610" (I can cut/file to length) of WR90 waveguide.

  Anyone know of source??
