Anyone built a Can-tenna?

Are they a cheap possible solution for remote rural communities with poor mobile phone reception?

What frequencies do mobiles operate on?

A cantenna is a directional waveguide antenna for long-range Wi-Fi used to increase the range of (or snoop on) a wireless network. Originally built using a Pringles potato chip can, a cantenna can be constructed quickly, easily, and inexpensively using readily obtained materials:

Four small nuts/bolts;
A short length of medium-gauge wire;
A tin can roughly 8 cm (3.66 inches) in diameter, such as a Pringles canister. The longer the better; and
An N-Female chassis mount connector, available at many electronic supply stores.

Interesting subject.

OK, I understand the antenna, but where does the wire go for the cell to use and how long is that wire, (length  = frequency), as you asked ? Can this be a long line like for 2 meters and directional?

Come on guys, what\'s the answer? Also, is a longer can more directional, narrower beam meaning better?

Another question, if the N-Female was installed at the back of the can be more effective? Underneath seems to me to cause more bouncing around before leaving the antenna.

Actually what I\'m REALLY looking for is a an inexpensive repeater antennae for mobiles for rural local so all community can benefit

But I had to start somewhere and came up with this via wikipedia (for single mobile phone - but probably makes the phone slightly less mobile  :D )
