as thread says, if somebody knows, i want to know it too. ive searched and searched, but 24dbi is most powerful wifi / wireless antenna they produce. im not talking about custom ones that can go beyond like 500km or more. its extremely hard to build one on your own as i have stated in other topic, but i really want to know why is 24dbi most powerful out there.
is it illegal to produce more than 24dbi or something ? factory details about 24dbi grid / dish antennas is that it can get signal from about 2500 - 4000 meters on straight line, which is very good indeed, however cant even start to compare to the ones that can go beyond 500km.
so why is 24dbi most powerful you can buy in shops ?
