does this product compatible with UBNT’s basestation antenna? because i recently have 3 units basestation break their Rocket M5 radios, and i haven’t replaced any of them yet.
one more question, so R11e-5HnD could be used to extend 1 radio on this board, so we can use this for 2 basestation antennas?
YES to both questions, although you might need longer antenna cables for this setup. RP-SMA should be easy to come by, just replace your antenna default cable with a longer one.
i thought the board outputs for antennas are RP-SMA?
SORRY, early morning mistake 
Fixed .
unfortunately, www.mikrotik.co.id don’t have them yet 
The RB912 or the longer pigtails?
both. although, the pigtail is not a problem anymore, i already a store on ebay, with variety connectors option. is this the right one?

also, if I add R11e-5HnD, am I going to need 2 of this?

one more thing,
RB912UAG-5HPnD + R11e-5HnD are not going to interfere to each other? as they are working on the same band, and too close to each other. i’m planning to use them on different channel though
thanks for the assistance
i am desperately looking for this unit, but can’t find anywhere close to my region
