Certification for antennas

Hello,

is possible to get “certification” from Mikrotik company for external antennas? We need a list of “recomanded” antennas from manufacturer (Mikrotik) for your radio devices (RB711,411,Groove, .etc).

The following problem is:

Out local authority (telecommunication Authority) do not allow connect any antenna to RB Groove (for example). We need certification (recommendation) from manufacturer, that we can connect specifically antenna to your device (Jirous, Tyhan, .etc). Without this, all radio routerboards are out of our regulations.
Thanks!

Such recommendations are inside the CE/FCC certification section of the info sheet of the products. See last page:
