suggested routerboard for 5 Ghz point to point

I am new to using Mikrotik for fixed wireless capabilities but I would like to ask any suggested for a point to point wireless link roughly 5-7 km. I am mainly concerned about antenna’s with a narrow beam width, which I am unable to find on the main mikrotik site. Anyhow looking for options to use routerboards with external mimo antenna’s with higher gain 19-23 dbi.

Thanks in advance.

Hi,

We have used the Jirous parabolic antennae for some PTP links quite successfully.
E.g. Model Link - http://en.jirous.com/antenna-5ghz/jrc-24ex_mimo

EDIT

The choice of Routerboard and radio card depend on the amount of bandwidth you want to carry.

Rgds,

Check WiBOX system:

real 20 dBi dual polarity http://www.wireless-instruments.com/en/produkty/15/44/antennas-5ghz/mimo/directional/wibox-pa-m5-20hv.html

and

real 24 dBi dual polarity http://www.wireless-instruments.com/en/produkty/15/45/antennas-5ghz/mimo/directional/wibox-pa-m5-24hv.html

Thanks for the suggestions. So i basically need to decide on a routerboard with dual sma connectors on the 5 Ghz band and decide on the antenna which was suggested.

Thanks again.
