Wireless card plus antennae which work

I have a Jetson Nano. The wireless card is Intel Dual Band Wireless-AC 8265NGW
I recently bought a nice pair of antennae with IPEX connectors

I simply cannot get these to fit. Please can someone recommend a working wireless card and antennae combination?

Hope someone has such experience. BTW, the socket on board is i-pex, 20579-001E.

Thankyou for taking the time to reply. Thsi indicates that I have the correct connectors - it is my thick fingers which are the problem!
