COAX Cable length 1.5 meters


There are many threads and articles suggesting the optimal length for a digital coax cable to be 1.5 meters (or a very short length). Now, what I am submitting to the those in the know, couldn't that length change depending on the materials used to manufacture the cable? Let's assume the cable has BNC connectors and measures exactly 75 ohms.

Belden coax w/ BNC uses a copper conductor and a tinned copper braid and a double-sided aluminum-on-polyester foil shielding. Recommended length by users is 1.5 meters.

The cable I am interested in comes terminated as 1.3 meters. It is OYAIDE from Japan.

The conductor is pure silver, with a Teflon dielectric and Foamed Polyethylene insulation. Shield is Copper foil + Silver plating copper. So, I ask you, wouldn't the materials influence the timing of the signal and thus the optimal length?

Also to ad to Al's comments, make sure it's proper 75ohm cable as many are 100ohm, and yes the bnc connection is a 75ohm, where rca are not.
