Awhile back Ken Swauger built some of us analog cables out of a RG62a/u 93ohm cable with Kens help i tried to find some of this but it is no longer made with solid copper center conductor. In researching this cable some of the cable had "Velocity of propagation" numbers some had a 66% some higher 79% can someone enlighten me as to what exactly this means? Is higher better or lower better,will it have any effect on what I'm planning on using it for? I'm making 7.1 intewrconnects and running some longer runs for video/audio. I'm leaning toward Canare wire of these two designs LV-77s and L5-CFW both with the Canare RCA's.
In looking at Beldens site and at all the Coax is where i seen the "Velocity of propagation" numbers but also noticed it on some of the Canare.
