With MMCX or U.FL connectors. You could by antennas -- RP-SMA, N-type, any. All of this you could buy locally, in city's computer stores. Not in everyone, but there are several big ones, which have such parts. And NO ONE sell pigtails! AT ALL! Personnel doesn't understand, what I'm asking about. One very special place offers custom-made cables -- any connectors, any length, but for short U.FL <-> RP-SMA cable they ask $30 (USD). For one.

Is that good or bad? I'm not sure :) It means, that my previous card is not broken (it is good), but it means too, that my environment is very noisy (it is bad) :) >> ar5416PerCalibrationN: NF calibration didn't finish; delaying CCA > Ignore that.
