But you don't want green-turning, bare copper shielding in aircraft RF
cable, or you'll need a gas-tight BNC connector. Also,
double-shielded cable (RG142?) poses a problem in finding and making a
correct BNC termination. The link below has good tech papers, by a
supplier of wire and cable to the avioncs industry. They discuss bend
radius, moisture, heat, connectors, plus usual stuff about loss,
reflection, capacitance, delay, etc.. Way overkill in places for VHF
comm, but in relative plain language.
