I was wondering if I could switch out the antenna that came with the Gigabyte - GC-WB867D-I PCI-Express x1 802.11a/b/g/n/ac Wi-Fi Adapter. Is that possible to get any antenna and screw it on the same way on the connectors of the slot? Can this result in poor speeds? am I forced to use only the antenna that they provided, if i needed a replacement or wanted something that looked different for design purposes?
