RT-AC3200 Which antenna for which radio?

[Matt Martin]

Hi everyone. This is my first post. I have the router mentioned in the title. I was wondering if the three radios on this router each get two specific antennas or if all three radios each use all 6 antennas? The reason I am asking is because I want to push one of the 5GHz SSIDs to another end of a building to a Netgear Nighthawk EX7000 range extender and the concrete walls are causing weak signal. So the plan is to get two antenna extension wires and mount two antennas from each on the outside of the doors to each room with the extension wires simply running thru the door mail slots so they have direct line of sight to each other down the long hallway.

They're shared and work together in context...

In addition to sfx2000's reply you would likely lose more signal strength through several meters of coaxial cable than you would gain by the relocation.
