Skin Effect - John Portune - W6NBC

Stranded wire makes sense for skin effect, but being they are all bundled together it stands to reason a lot of their circumferences are touching, due to this I wonder how much percent more surface area is really available? For myself, I'd use stranded if even only 10% more surface area. We could just work it out with geometric math, I will be looking into this more but I've never been very good at geometry, does anyone know?

I wonder the same thing. I don't think you get any more surface area with stranded. since the individual wires are all touching, it's just one big conductor.

Found this Very interesting, surprised you only have one comment. Knowing about the skin effect, I have been wondering how a full wave loop in the diamond configuration fed at the bottom, with Rg 59 and 1:1 balun. Constructed out of copper tubing or let's say 1/2' EMT rigid steel conduit at 10-12 meters? Perhaps, PVC with your foil tape idea didn't think of that. On a side note; I happen to use an Alpha LM-400 Equivalent that has a Stranded center conductor, they advertise the Skin Effect, as well as its flexibility. 73

John has been a legend in the actual science of antennas and RF for a long time and I agree, very surprised that there is not many views.
