Sorry,
I am not an expert , so i thinked was possible a lot of value of carachteristic impedances...

so only 50, 75 and 93 ohms and this ( take from wikipedia):
-------------------------------------------------------------------------

Biaxial cable, biax or Twin-Lead is a figure-8 configuration of two 50 Ω coaxial cables, externally resembling that of lamp cord, or speaker wire. Biax is used in some proprietary computer networks. Others may be familiar with 75Ω biax which at one time was popular on many cable TV services

--------------------------------------------------------------------------


Majbe the only possibility i has had (in the past only )was the /VAN DEN HUL S-VHS 2/75 that , unfortunately , is not more in production.

I'll searh to contact V.D.H., to see if some distributors/ shop/ has some of this precious cables, for me.

VDH s-VHS cable is 2 x 75 ohms, and S-VHS cable is still available from other sources.
What are you using the cable for, would help.

As suggested, googling will get you dozens of possibilities.

Belden Twinax is the only 150 Ohm coax I know of. But it's not solid core. I think the Triax video cable is still 75.

Why solid core? Stranded will make life easier and is routinely used in mission-critical applications.

VDH will empty your wallet with great efficiency and get you something that works no better than Belden and potentially worse.
