I got interested in cantennas, is what this is all about.  Basically 
take a used can of some suitable size, with one end cut off, put a 
1/4wave antenna 1/2wave from the closed end, and you beam your RF signal 
directionally out the other end.  So you need to run cable from the 
router to the 1/4wave antenna -- the stuff in the page you cited seems 
just what I wanted.

A purpose-built plastic cap to keep out weather would be the crowning 
touch.  What I have found is that there are a bunch of standard can 
sizes that all don't quite fit each other.  A juice can seems like it 
would be better than mediocre at 2.4GHz.  Gatorade powder comes in a 
stubby metallized cardboard can with a recloseable lid that's just a few 
mil too big to close a juice can.  In extremis, duct tape can make 
anything fit, and that might, finally, be the way to go, if the dollar 
stores don't have the right stuff.

     Thanks,        Mel.
