I saw many posts on adding external antennas to MR600. But i didnot see an one posted their setup.
I have bought this router for my native which is a very remote place. without external antenna nothing works here.
You can see my complete setup in the following link using MR600 and external antennas.
Antenna -Grid 24Dbi+12Dbi LPDA-MIMO config
Cable-43meterX2 0.5 inch Feeder cable
Hope this helps to buy this router for remote inetrnet application. cheers :).
Reach out to me if you guys have any doubts :)
