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
