BNC Cable is RG6 the best?

BNC Cable is RG6 the best for Digital transfer?
I received a AfterDark Clock to mate with my EtherRegen. With it came a very cheap looking BNC cable.
I'm not sure exactly what makes up a BNC cable special. I know it should be 75 ohms and shielded.
So, what about using RG 6 cable? I have the appropriate BNC fittings.

Should this be better?
And of course, why then are some of these cables so expensive?

There are versions of RG6 with single dual or quad shielding.  Other than that, the difference between different cables with the same characteristic impedance is high frequency loss - not important for short distances.  Cheap looking cable, as well as RG6 might be fine.  The most important is characteristic impedance matching, especially at the end (DAC).  You can find some info about different cables at Wikipedia:  https://en.wikipedia.org/wiki/Coaxial_cable

kijank,
I would probably be looking at a .05M finished cable.

I'm not sure it's possible to make a cable that small....

@ozzy 0.05m = 5cm ????

If you can make such short cable then you don't have reflections, no matter what you use.

Sorry slip up, wrong decimal point.
.5 Meter (or 1/2" Meter). I suppose I could go to 1 meter if it matters.
