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.
a 10" x 10" diamond with flattened corners.

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?
