It is a for for diversity reception, and has also been a thing since pic. related was hot.
>Any frequency low enough to see benefits from the added bandwidth is necessarily low enough to where MIMO wont work.
You do realise I hope that you get reflections from the ionosphere, aircrafts and meteor trails?

Part of the hobby is exploring new tech, and fading has always been a hassle.

I was not aware of any airsoft that was a service, did HF radios or even Morse code.
