I don't normally spam the list with commercials, but some of these
prices here are NICE.
We use the RB912 (MIMO) for back-end links, but presently don't need
any more.
The OmniTik is at an incredible price, especially for something with
a built-in 5-port switch and MIMO! Just know this is NOT the
gigabit model.
The RB2011UAS is a powerful home router with "1W" (500mW * 2) 2.4GHz
MIMO AP capability, all-metal construction, and TOUCH SCREEN.
Ooooo. Note: the power brick on these does not detach from the
router by default.
And for any outdoor omni 2.4GHz applications, the $25 9dBi Laird
antenna ... I don't know where you'd find anything cheaper.
