Question Are all M.2 cards have same anntena connection size

[MeGroot]

I have a mid-size mini card and want o replace it. I purchased a mini card but the antenna connection wires are to big. Do I need some type of adapter or change the antenna wires.

Return it and purchase the correct card?

In this case copper is copper. Purchase the connect connector and attach. Can even solder the dang thing, this thing likely to stay put once is attached.
