A QR .860 and a QR .715 cable have the same V.O.P.(.88) but are different size cables.
> Well we know that. I didn't think it varies by 2 or so ohms, but yes we know that. Just like all of your actives/passives/ hell even splices, splitters, barrels, are rated with a return loss. (hopefully at least by 20 db) meaning that you'll have a signal 20db low of the injected signal reflecting back towards the source. The higher the return loss rating, the closer to a true 75 ohm device you have.
