Hi all,

I got my hands on a LHG LTE6 kit (RBLHGR&R11e-LTE6), and I cannot find if this is a 2x2 MIMO antenna device, I have seen the inside and with it having two antennas, MAIN and AUX, does this mean it can do 2x2 MIMO, or how does this work?

yes, the R11e-LTE6 is a MIMO 2x2 device, it have a two connectors for two antennas.
You can just check the webpage to cofirm this, means you not must open a device.

as bonus this are a MAIN connectors at PCB of SXTR and LHGR

Ah thanks for the clarification, it wasn't clear if it was a 2x2 MIMO, even from the product page.

Single antena is 150Mbps
Double antenna is 300Mbps

Product page say about Cat.6 can reach a max 150Mbps.

If you read about modulation (per one antenna) you discover

RJ45 port tho is only 10/100 speed
