Cantenna for PC Card or USB?

Archived from groups: alt.internet.wireless (More info?)

I'm looking to get a cantenna, probably from www.cantenna.com and it's
for a notebook computer, which means a PC Card to connect to the
cantenna would be preferred. Also 54Mpbs (11g) would be preferred.

I cannot find an 11g PC Card with a connector suitable for the
cantenna, although Zoom do one for 11b. What would be a suitable
manufacturer, please?

If there is no such creature, which USB Wifi unit would be most
appropriate and good performance for the cantenna? Thank you.
