The photos shown here document our installation, made in October and November 2003, of a wi-fe network between two house about 300 meters farm with some trees in the middle. We managed to reach, with due D-Link DWL-2000AP access points, an average spped of 17 Mbps, which actually seems the maximum achievable with those models. Without the dish, that is to say only by using two cantennas, we reached 15 Mbps spped.
We are me, my brother Alessandro and our friend Gliano.

Alessandro on the top of the roof beside the
dish used on one of the sides of the wi-fi bridge. It's a nice 1 meter and 80 centimeters disc, made by Fraccaro, which was in the past used for satellite TV. You can see Friuli mountains on the background. |

Detail of the cantenna which serves as
illuminator for the dish. The access point is contained into the rectangular metallic box. |
 |
Detail of the cantenna, from the bottom. You
can see the two cambles (power and ethernet network) which descend; also, you can see the cable which connect the access point with the cantenna. |

The trees located between the two points of the
bridge. It's about 200 meters far from the side in which the dish is installed, and 100 from the other. |

i saw the cantenna and definitely i was so surprised that a single equipment and a can can be used as an antenna for wifi.. i just want to know more about the cantenna like what would be the needed things etc.. i hope that i could have a feed back or your reply to my message thanks
Hello casem!
Building a Cantenna is quite simple, but you need some basic instructions in order to do it properly.

Michele.
This is my intro into you learning to build your own cantenna. I started my idea of making my own website for building my own cantenna guide was when I had difficulty in making my Pringles cantenna there was so much mat and proportion in making it. So I decided I wanted to make a simple Guide to success. . My name is Dean K. my email is firefades@gmail.com please send me an email if you have a queston.

I have been building & designing wifi antennas for years. The best I ever used was a coax feed 24dbi parabolic grid. The Yagi was another good performer. It takes very little to build a cantenna or to improve your wifi signal. A simple way to improve a USB wifi adapter is to place a metal pie plate behind the adapter then check signal. Move the pie plate in and out until you find the max. signal. I have built a very simple device using this idea. Check it out at www.wificantenna.net
