Long live the Pringles cantenna
-
pringles can is too small for 2.4ghz cantenna,it's near cutoff frequency but just barely, you need 10cm-ish diameter can or shorter 16cm-ish can-
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 https://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. cookie tin is 15cm dia 8cm tall and it works, but size can vary a bit. you can copy or scale slightly designs of 13cm band antennas
-
helical antennas work fine too and look goofy as hell
