Model: AX11000

What is the name of these press-fit antenna connectors?  Form factor wise they seem like a variant of SMA or RP-SMA connectors, but without the threads.

My router is wall mounted, so I need to be able to reposition the antennas for a bit better coverage AND to make it fit inside the in-wall network cabinet.

I am hoping to either find a second set of antennas that I can deshell and free mount the loose antennas, or find short patch/extension cables so I can do the same with the existing antennas. 

I'd just deshell the antennas that came with it, but I don't want to have to explain that if the RMA happens later because it seems like every company loves to use completely unrelated factors to get out of warranty repairs.

Appreciate any help or information provided.  Thank you.
