Murray,


Solid copper center conductor has more uniform resistance across all frequencies whereas copper-coated steel is physically stronger but shows "skin effect" favoring higher frequencies.


Basically, copper-coated steel center conductors are not as good from d.c. through lower frequencies up to about 50 MHz, so it's less desirable for sending power up to antenna LNB's or preamps plus not as good for return "t-channels" (frequencies below ch. 2 which cable systems are using for cable modems, etc.).


If strength is not a consideration, solid copper is better.

Should I use Solid Copper -or- Copper Clad Steel Conductor RG6 Wire when installing a Dish 5000/HDTV-DiercTV-HDTV/UHF OTA system?
