Going to be experimenting with putting this in my Razer Blade 14 soon. In laptops, there are no 3x3:3 AC setups outside of Apple that I know of. Wireless card is an AzureWave AW-CB160H, which unfortunately sports three MHF4 antennas, and I intend to re-use two of my computer's internal U.FL antennas. So, I made two little adapter pigtails. The third antenna pictured is a dual band PCB antenna from eBay with an MHF4 connector already. Will post results in a few days.
