Sand casting. I can copy stuff in half hour if the draft angles are correct.

You can almost do that now. I saw a demo at the Maker Fair last year that was
pretty much a 3D printer take-off on the lost wax method. You print the shape
(aka model) with a special plastic. Then encase the model in a breakable mold.
Then heat the mold to evaporate the model, then fill the mold with the metal of
your choice. Break the mold, and viola; a hard metal one-off.

Sounds like 3D printing is the direction people are going for one-offs.

When I was building slotted waveguide antennas for our network, we needed
a way to seal up the slots so the rain wouldn't fill the antennas faster than a
weep hole could drain it. I found that 3M made some heat shrink tubing that
just fit over the size of tubing I was using. After heat shrinking the stick,
we would dip the ends in "plastidip". Never had a leak. I wonder if you just
needed to hand make a couple dipole or patch array antennas, if dipping them in
plastidip wouldn't be a decent option. Obviously it would be labor and time
intensive for production, but for a couple one-offs, why not?

Yup. They have an array of metal circles on a board connected to each
other by traces.
What about a cheaper external antenna? The price to beat is $120.

Yeah, that will be an array of patches inside. Hard to couple to
with any efficiency.

Like a 45 slant 15dbi panel.

I want to narrow the radiation pattern on Wimax CPE in order to
reduce interference. Higher gain is a bonus, but mostly I want to tune out
interference from other base stations and thereby improve CINR.
Right now all I've got is I can put an external antenna on with
coax jumpers. A dish with a significantly narrower pattern than the integrated
panel is $120-$140 from KP Performance, plus the cost of the coax jumpers and
the labor to seal them.
I'm really missing the Canopy stingers and reflectors right now.
If I could slip something on for $50 I'd be all over it like white on rice.
I'd also just settle for a cheaper external antenna.
Any brilliant ideas?
