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.
