I'm sorry, no answer to your question, I just think it's funny,
remembering the Heath Cantenna, that someone expects a Cantenna to
actually radiate a signal.

I have a Heath Cantenna too, but the WiFi folks mean a different thing
with
that term -- a 2.4 GHz waveguide antenna made from a Pringles (tm)
can.
Unfortunately, that cantenna of the second kind has almost no gain.
It needs
a much larger aperture to make that gain than the 3-inch diameter of a
foil-
covered paper tube. *That can be had by attaching a larger, metallic
funnel
to the mouth of the antenna to form the typical microwave horn
antenna.
See any reputable antenna text book for design details.

Just about anything works better than the Pringles(tm) can that made
the antennas famous. I made one with a large fruit juice can and it
worked fairly decent. I picked up about 10 db compared to the stock
antenna.
