Re: How to detect signal

said by public:

No such thing.
Additional 20dB antenna gain would remedy the problem.

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..

Just modest 2ft size, depending on frequency.

I think it was "additional 20db" on top of whatever 2.4ghz antenna he used for his site survey.

2ft dish adds about 20db to 12cm 8dBi patch at 2.4GHz

Um no. A 24 dbi 2.4 GHz grid dish is about 30" x 24" and weighs about 5 pounds...

A 27 dBi solid Parabolic at 5.8 GHz is about 20" in diameter and weighs about a pound...
