To all the avionics-buffs out there in glider-land:
What is the proper designation for the type of microphone cable used to run from the 'Becker-' or 'Dittel-' speaker box to the radio on the panel? The one sample I have has two wires (white and brown) surrounded by a copper braided shield plus two fiberglass strands - presumably to add tensile strength - in it. Need a few feet of it to avoid splicing it.

Thanks,

Uli
