No such thing.
Additional 20dB antenna gain would remedy the problem.
Lol thats one huge ass dish
At risk of starting a debate (that is NOT my intention though), I wanted to reply with a more serious answer..
Ham's actually do use 2.4ghz for "moonbouncing" signals, It's also referred to as "EME" for Earth Moon Earth..
Granted it's a whole different ballgame shooting a signal over ground vs the perfect line of sight example I have given.. But with the rather intense and sometimes huge antenna's or antenna arrays, it can be done..
