There are lots of plans on the web for building WIFI antennas. Try searching on "pringles can antenna" or "cantenna". I have a Cantenna I bought from ebay. It works great and it even came with a tiny tripod that fits on the desk. 73, Ken -N5SWR -----Original Message----- From: For blind ham radio operators [mailto:[log in to unmask]] On Behalf Of Gery Gaubert Sent: Friday, January 12, 2007 3:21 PM To: [log in to unmask] Subject: antenna building I am studying for my general class license. I got to the chapters on antenna design. I find this very fascinating. I am curious now. If you can build an antenna to work for ham radio, can you build an antenna to work for a wireless router? If not why?
