Slotted waveguide

[Lyle Williams]

Thanks to those who provided advice on the best way to cut slots for a
waveguide.

In the end, I bought a trimmer (small router) - it cuts the 3mm aluminium
well.

I have built my first slotted waveguide, and I am evaluating its
performance.  The first waveguide took about four hours to build, but a lot
of this time was me working out the best way to do things.  Some time also
went into sorting out a jig for cutting holes.  Now that I have learnt some
lessons, I could probably knock out four 16+16's in a day without too much
trouble.

If anyone has access to good elevated sites in Canberra, I'd be glad to
donate waveguides to hub projects.
