can I use Nstreme Dual with 2 antennas for each RF card?

RouterOS Wireless Networking
1

I will explain -
now if I’m using 1 RF card with 2 antenna connection (R52n-m)
I can use 2 antennas and config him to use
HT Tx Chains: chain0 chain1
HT Rx Chains: chain0 chain1

is it possible to the same thing while using the new nstreme Dual?
maybe in HT Streams? some how ?

Thanks ,

Nstreme dual use two wifi modules, indipendently how you configure them,

yes, you can use both chain rx/tx on both wlan, but it working accordling the nstreme dual protocol (one only tx on both chain, another only rx on both chain).

O.K.
I have no problem
can you show me how to config it on the Nstreme Dual?
what do I need to put on HT Streams? both\double?
and also channel width? 20/40?
because now (with single antenna in both side) I get only rate of - 54Mbps\54Mbps
and if I work in NV2 Ap–Station I get much better rate ~80 (2 antenna HT0+1)
the distance stay the same ~ -60/-60
so its seem it better to work on NV2- I use only 1 RF card in each router,and better performance,no?
or that my configuration isn’t correct?

Thanks ,

one thing are nstreme, one nstreme dual, and another is NV2.

The best is NV2 HT RX 0,1 / TX 0,1 5GHz-onlyN 20+20 (20Ce) [and use RouterOS 6.15] if you have one dual polarization dish/antenna on both side

If you active HT 1 on tx, you broken the radio, because one antenna MUST be attached to channel 1 (2nd channel)…

so to see I understand , you say that
NV2 is better then nstreme\nstreme dual?
really?

I use it on my production environment…

o.k.
I have now mange to work MIMO 2X2 on both side
open the HT and there is 3 options:

/interface wireless nstreme-dual set ht-streams=
both  double  single

single - it just to use the default antenna , I get it
what is the different between double and both?

didn’t find the answer in WiKi

Thanks ,

you can not use nstrame-dual with only one wlan for routerboard on each side,

you mut use nv2

I have 2 card in each RB
