[Antennas] Copper clad 7-strand vs 19-strand tinned?

2003年7月27日 12:27:24 -0700 (PDT)

I've decided on the perfect open wire spreader (3/8"
black irrigation tubing) but when I made some long
runs of this w/ 14AWG 7-strand hard drawn copper wire
they were TOO HEAVY for my applications. I support
multiple antennas on a single rope run between two
tall trees, weight is of a large concern.
So, I'm thinking of going with 14AWG copper-clad steel
which is much lighter.
Anyone use these wires from DavisRF?

Their #:
WM523 (14AWG 19-strand tinned copper clad steel)
WM511 (14AWG 7-strand copper clad steel)
The tinned 19-strand is nearly twice the price but
sounds like a very long-term solution. I run 1500W on
10-160m, gotta have the 14AWG wire.
Anyone use these or have comments on copper clad
stranded for feedlines? They use this kind of wire in
the 450 Ohm PVC-covered commercial line and it's very
lightweight but changes too much in the rain/ice/snow
for my tastes.
