In Reply to: Antenna cable? Copper clad steel centre - for RG6 - WHY? posted by Timbo in Oz on July 25, 2012 at 04:18:09:
Copperweld is used for strength, cost and group delay. In my wayward youth I used to use it for 80m dipoles through the oak trees. Copper stretches, sags and breaks when the first small limb falls on it.
Most RF current is on the outer surface anyway and a core with perm forces that to happen at lower frequencies. I've mulled over using it for speaker cables, off-hand it seems like a terrible idea but I wonder if that's really the case? Anyway it works great for RF.
