Some of the specs I gave were MIL.  The voltage specs were CECC specs.

at 70,000 feet the N connector has the following voltage specs:

Working Voltage for RG-213: 400 Volts.
Working Voltage for RG-58: 250 Volts

Dielectric Withstanding Voltage for RG-213: 600 Volts
Dielectric Withstanding Voltage for RG-58: 350 Volts

Those are the only altitude related specs.

OK, for BNC:

VSWR 1.30:1 max (straight) up to 11 GHz
Insertion Loss (straight): 0.2 dB max at 3 GHz
RF Leakage: -55 dB min from 2-3 GHz
Insulation Resistance: 5000 MOhm min.
Contact Resistance: Center: 1.5 mOhm, Outer 0.2 mOhm
RMS Voltage: 500 VRMS max, at 21,000 meters: 125 VRMS max
Withstanding Voltage: 1500 VRMS, at 21 KM: 375 VRMS
RF High Potential with standing Voltage (5 MHz): Sea level: 1000 V RMS

That's all I have on BNCs.  The MIL spec is: MIL-C-39012 C.
