We have made a 15km link test with two SXT G5hnd devices. If anyone interested (use google translate)
congratulations, very good result!
Yeah we think is a good result too. Do you think with larger SEXTANT we would get even better result? Or any other MT?
We announced new SXT HG with better antenna: http://www.mikrotik.com/download/share/hr13.pdf
Maybe that will improve your signal
Yeah we were there 
Now we are just waiting that new products will see the light
I recommend RB911G + our 20dBi dual pol panel → http://www.wireless-instruments.com/en/produkty/15/44/antennas-5-ghz/mimo/directional/wibox-pa-m5-20hv.html . Big installation compartment, when MT will launch stronger board, you can change it without any problem
What type of MIMO antena does WiBOX have? How does it look inside? Is there place for RB inside too? “Radiation Pattern” seems same as in the SXT.
The complete series of PTFE dual polarity is designed by our company designer, so there is no possibility to have same antenna as any another company, there is 3 versions:
20 dBi - http://www.wireless-instruments.com/en/produkty/15/44/antennas-5-ghz/mimo/directional/wibox-pa-m5-20hv.html
22 dBi - http://www.wireless-instruments.com/en/produkty/15/54/antennas-5-ghz/mimo/directional/wibox-pa-m5-22hv.html
24 dBi - http://www.wireless-instruments.com/en/produkty/15/45/antennas-5-ghz/mimo/directional/wibox-pa-m5-24hv.html
there are real dual polarity antennas, not 2 panel antennas side by side. There is a lot of space for RB, depends on the WiBOX model (Medium, Large, Extra Large - http://www.wireless-instruments.com/en/3/wibox-series.html).
Tomorrow I will tell to technicians to take some photos of the WiBOX inside, I don’t have any on this laptop.
No offense but this is not an advantage, from my knowledge two antennas will always be better than an mimo one. An if there is one mimo Antenna Gain should be 27dbi not 2 x 24dBi. This is confusing.
I regard your opinion, but we have checked few solutions made of antennas side by side with our design, we were always better. The fact is that we compared this one http://www.wireless-instruments.com/en/produkty/15/44/antennas-5-ghz/mimo/directional/wibox-pa-m5-20hv.html with 19 dBi dual polarity antennas. The diference was in materials used for the antenna PCB board, our antenna is made of PTFE teflon laminate, the antennas which we compared with were made on FR4 substrate. There is a possibility that single polarity antennas were poor, so the solution made of 2 was bad, or the combination was made bad, but we didn’t consider it as a problem for it’s not our business.
Maybe if we compare our products with made in the same materials and technology, the result would be different, but the global trend is to minimize antennas.
Interesting debate! If everything goes as I expected, I will do test with MIMO and two antennas, and post proof of better signal, and better everything, if you would be interested!
I think there is a lot of people interested in the comparison which you mentioned.
Has it got the same cable entry with snap to lock removeable cover as in the original SXT - is there a option to mount a waterproof ethernet socket?
Waterproof ethernet socket? 
it’s inside, so if water doesent come in it IS waterproof 
RJ45 with rubber around isn’t waterproof
I directed the question to Normis as he listed a product which is available in may http://www.mikrotik.com/download/share/hr13.pdf , so unless you have used SXT HG i am not sure you can answer my question?
Also water does penetrate into the internal rj45 socket and then flows down inside the cat5 cable in certain climates – just search the forum for others who have experienced this
http://forum.mikrotik.com/t/water-sxt/53217/1
Just for clarity waterproof ethernet socket refers to this

Respect as for the “red letters”. 
Now, one MiMo antenna “acts” as 2 different ones. You won’t see any differences in signal or anything else - BUT the MiMo antenna MUST perform OK. - for the guys interested.
If MiMo antenna performs right, you don’t actually need 2 antennas.
The best is to try these antennas and see the difference “up close”. Used materials is the key, on the standard FR4 substrate it’s almost impossible.
