    It’s getting harder to find metal cans of the right size. More and more packaging is cardboard. But the cans that are used to package premium Whisky make excellent WiFi Cantennas.

    What about the can dimensions for a 800mhz cell tower? I get can get a random signal in my house, all I need is a little boost. Any suggestions?
