I have looked everywhere, and I cannot find a specificationIntel Wireless-Ac 9260 antenna connectors

I have looked everywhere and I cannot find a specification for the connectors that connect the antenna to the WiFi card. Can anyone shed any light on the specific type I need? I've ordered 3 sets now - only one fits, bit that set won't work in the situation I need it (space constraint) and I tried bending the connector on the pigtail and ot broke. So I'm looking for a roght-angle connector in the right size.
