Thank you for your interest in the Intel Aero Compute Board.
In regards to your query, the guide you are following: http://www.instructables.com/id/Intel-Aero-Drone-Extending-Wifi-Range/ specifies the Antenna connector type that is recommended.
It is hyperlinked in the guide at step Step 1: Collect Materials.
Let me know if this helps.
I tried this myself, and the instructable is pretty misleading. You need to get IPEX MHF4 to SMA/RPSMA pigtail, NOT and IPEX MHF1 because it doesn't fit. See my post here:
