[Elecraft] BNCs

[Myron WVØH]

All,

And while the pin/receptacle dimensions are important to maintain physical integrity, the characteristic impedance doesn't come into play unless you experience a "considerable" phase length such as a 30 degree discontinuity at a given frequency. 

So at HF the phase length of the 70-50 Ω discontinuity experienced by a BNC connector (or any other impedance) is very short. Important at UHF, yes, important at HF, nope.
