RB751U-­‐2HnD + external antena

Hello
is it possible attach parabolic antena 24 dbi + 15 meter cable length to RB751U-2HnD?
thanks

In my experience the external antenna port on the RB751U does not work properly at all.

See http://forum.mikrotik.com/t/rb751u-external-antenna/52826/1 for more information.

thanks dear for reply.
