Default WS #19 RF cables impedance.

Daniel, use RG-11 coax.
I measured the dimensions of the original coax that fitted the Pye connectors many years ago and that gave 75 ohms of impedance.
And, a RG-11 coax have the same dimensions as the original ones.
RG-8 can be used also, as the lines are too short to represent any mismatch.
Variation in cables capacitance will be balanced by the variometer anyways.
