FWIW, here's an old post by W8JI from July 2003. The thread doesn't
indicate whether these figures are published or measured, or the CommScope
p/n.

RG6 CommScope Cable solid copper center conductor loss
vs. copper clad steel (in brackets):
MHz dB/100ft
1 .20 (.26)
10 .76 (.81)
50 1.46 (1.46)
100 2.05 (2.05)
200 2.83 (2.83)
The difference is undetectable at HF.
DC resistance solid copper is 6.4ohms/kft, CCS is 28.6ohms/kFt
I'd even use it for video, unless I had a LONG cable that
was also carrying current to operate the electronics.
100ft would dissipate less than 120 watts at 1500w
on 1.8MHz over 100 feet, or under 1.2 watts per
foot at 1500w. It will safely handle 1500w CCS
in open air on 1.8MHz.
