RG174 2 conductor equivalent?

Does anyone know of a two conductor shielded cable version of RG174?  Or something that would be similar to that ideal?
Thanks

Do you want independent shielding for each conductor? If not, then there are many dual conductor single shielded wires/cable options.

Do not know if there is a product on the market that has individual shielded conductors in one 'package'

Yes, two conductor with a shared braided shield.  There are countless options, my hope was that someone might know of something in the ballpark of RG174 in that arrangement.  Thanks!

I have some two conductor shielded cable on hand here that offers individual shields to the conductors, I believe it was designed for SVHS.

RG174 is a high frequency COAXiAL cable.
Two conductors sharing common braid cannot be coaxial.
What for me, I do prefer Canare L-2B2AT.

Not exactly what form you want.  If the two cores are not individually shield then normally you want twisted pair (often called balanced).

Here some common "styles"

Cheapest - two core coax

Better - mic cable (The Canare stuff DDD mentioned is much better quality.)

Dual Coax with overall shield [Sorry I'm not sure if that one has the overall shield, but you get the idea].

If really want RF cable then you might have to hunt around and will probably have to buy a reel.
For audio, watch out for the aluminium foil shield stuff.   Some of that cable can generate seriously high microphonics.
I've had cable made.  Cost isn't too bad but IIRC your looking at 300m to 1km.

According to the water analogy of electricity, transistor leakage is caused by holes.
