I use it to diagnose ppl's problems, finding ppl stealing wifi or nuking users. Like i'm about to nail the little idiots across street that keep nuking my customer's laptops as i turn them on in the shop. It's taken me 2 weeks to find 'em since they turn nukes on and off quickly. Now just to triangulate to make sure. fyi: - the larger the can [up to 4.8"] the more nodes/AP's you get but shorter distance you reach. Well you can go larger but you might as well use satellite dish - the smaller the can [min. 74 mm] the longer it must be and more precise the tuning when looking for AP's. ... good for up to 25km. Have fun trying to tune it into an AP though. Need a machine gun bipod at one end of can and other end a fine thread screw to go from one office to next way out in Vancouver. And same for vertical. - the more precisely you build your can the better reception it will have. - on 'instructables' website there's even a super antenna made of copper wire, styrofoam and brass plate. Not recommended for the novice but i get 15 to 25 km out of it. - you can use any older box or laptop [P1 or faster] for your admin and or wifi card - software: one that comes with card, net stumbler, easy wifi radar - paint it or protect it well since outside works best "do not paint copper wire inside can!" - roof or TV tower work best for line of sight. Some attics work great - you can use TV cable for coax but not as good as specific store bought N cable, you have 180 ft to play with ... shorter the better. - each can needs fine tunning ... have fun - to get better reception out of your can you can use added horn about same length as can - good idea to cover open end of your can really well with microwave resistant lid since birds love the idea of using it for their nests. One fried my NIC card twice before i figured it out. - you can use satellite dish to extend your reach ... up to avg of 70 km [hope you live on top of mountain], i think world record is 128 km Enjoy that was fast, thanx :)

My large juice can reach 1 to 8 km line of sight, less if it bounces off objects. I use it to diagnose ppl’s problems, finding ppl stealing wifi or nuking users.
