I once made one of these with a bigger can and mounted it on an old 10’ satellite dish. Managed to get Wi-Fi across several thousand yards without issue
wait i thought for some reason that pringles can sized waveguide would have cutoff frequency above 2.4ghz. nevermind, there’s something better because bigger aperture can get you more directivity like this lea.hamradio.si/~s53mv/wumca/cup.html i made two out of cookie tins and it works over 500m at least

We didn’t use Pringles, I think it was these big peaches cans

i’ve used the same (800ml can) and this one works well
