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.

What does the CPE look like?

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?
