I understand the comment on flexible and easier to work with.
My understanding is that the DCS signal is about 3.27 MHz (correct me if I am wrong please)
The only niggle here is that the strands in stranded wire are not independent, but a clump, so where they touch, it is like a larger conductor. (if they were independently insulated it would be much better)
But on the outer edges of the bundle of wires, I concur that there is more surface area, thus there should be less attenuation of the DCS signal.
Thanks guys, was just wondering on your experience.
