Journal TheSync's Journal: WiFi Cardboard Horn Antenna 2
I had my summer intern to build a cardboard horn antenna for testing long distance 802.11b connections. Here are three pictures of it: 1 / 2 / 3. It has about 10 dB gain over a PCMCIA card wireless NIC. The antenna is based on this design.
We tested it across the Memorial Bridge in Washington, DC. Not only were we able to get a signal, but from the DC shore near the Lincoln Memorial, we were able to pick up wireless access points in Rosslyn, VA.

The expensive part is the pigtail to go from your wifi device to N connector. Mine cost about $30, you have to be careful which connector you have. My Enterasys cards have "MC-Card" connectors. I believe Apple Airports have these as well. You should keep the pigtail length as short as possible, at 2.4 Ghz, even reasonable quality
